 T wilight heartthrob Robert Pattinson is dating Elvis Presley's granddaughter Riley Keough, a close friend of the star has confirmed. 
 
 
 
 The 27-year-old Brit was spotted driving around Los Angeles with the stunning redhead over the weekend. 
 
 
 
 And a source told MailOnline today that although it was early days, the couple had spent much of the last week together, adding: 'They're inseparable. Rob loves the fact that Riley is Elvis's granddaughter - that's true Rock'n'Roll royalty in his eyes.' 
 
 They now plan to spend July 4 together before Robert starts filming Map To The Stars in Toronto on Monday. 
 
 
 
 However, one person NOT so happy about the budding romance is Robert's ex-girlfriend, Kristen Stewart, who starred alongside Riley in The Runaways in 2010.

 Former co-stars: Riley, far left, is pictured with Robert's ex-Kristen Stewart along with Dakota Fanning and Joan Jett at the after party for the premiere of their film The Runaways at Sundance in Park City in 2010 The friend described the new romance as 'short-term lust right now rather than long-term love'. Although the pair had met before - through Kristen Stewart- they got to know each other better through events for Dior in May and June. 
 
 Robert is face of Dior Homme while Riley until recently was the face of Dior Cherie and still has ties to the company. And the source adde d: 'Riley was always Kristen's friend dating back from their time filming The Runaways but recently Rob and Riley been spending much more time together since meeting through their Dior modelling connection and Riley has stayed over at Rob's Los Feliz apartment. 
 
 'They have a lot in common- they both love LA, London, rock music and table tennis.' However, the friend said that Kristen Stewart, whose turbulent romance with Robert ended in May, was 'livid' with her former flame, adding: 'Kristen feels that she acted as mentor to Riley on her first film The Runaways, introduced her to Rob and encouraged her to make a career of acting. 
 
 'Rob has been made aware through friends that she is devastated. 
 
 'Kristen is emotionally volatile at best of times and flew off the handle when she found out about Rob's liaison with Riley. She's told Rob via friends she feels violated.'

 Riley - who was previously engaged to actor Alex Pettyfer whom she met on the set of Magic Mike - is the daughter of Lisa Marie Presley and Danny Keough. Riley has been close to Kristen and Robert, attending Kristen's birthday party at Mexican restaurant Cantina Malo in April. And at the weekend, Robert was seen taking the actress, who bears a striking resemblance to Kristen - back to his Los Feliz home. 
 
 Wearing a check shirt with sunglasses and what looks like a back to front baseball cap Rob was spotted driving his red Chevy Silverado truck ton Saturday afternoon accompanied by his pretty passenger - and a ping pong table in the back.

 Riley wore her bright red hair down and was dressed in a green T-shirt and was wearing large glasses. As Robert entertained his new leading lady a rather forlorn looking Kristen flew out of Los Angeles on Sunday evening. 
 
 She was later seen at the Chanel Haute Couture show in Paris looking stunning in a white jacket and short shorts. Meanwhile Robert joined the throng of celebrities who flocked to see Beyoncé at the Staples Center on Monday night. 
 
 Big role: Riley, seen right, played Dakota Fanning's character Cherie Currie's big sister in The Runaways Robert has recently been seen out with pop princess Katy Perry - another friend of Kristen's, leading to her wrath - however, he told friends there was no romance at all. 
 
 
 
 Hanging on by a thread: Kristen and Robert were still together last November after the release of Breaking Dawn 
 
 Indeed, the actor said Katy was merely helping him through the difficult break-up from Kristen. 
 
 Robert and Kristen are believed to have split for a second time after Kristen got back in touch with Snow White and the Huntsman director Rupert Sanders, whom she confessed to having an affair with last year behind Robert's back. 
 
 
 
 Robert may have something else in common with Riley. 
 
 His own musical efforts have previously seen him record two tracks for the original Twilight soundtrack, Never Think and Let Me Sign. 
 
 And he has also previously said he originally wanted to be a musician rather than an actor. 
 
 He said: 'I love the piano. I never really had any aspirations to be an actor when I was young. I wanted to play the piano in a bar, to be the old dude with a whiskey glass.' 
 
 The star revealed how he sl ump ed into a depr ession after rocketing to fame in the Twilight movies. 
 
 
 
 He said: 'I went through a big time of depression between 23 and 25, I couldn't go where I wanted to go. 
 
 'I was in the tabloids every day and I didn't have access to the roles I really wanted. I wanted more, on every level.' 
 
 Robert ound that while his co-stars in the world famous film, Kristen and Taylor Lautner, were off working on other projects, he was stuck in a rut. 
 
 He said: 'I finally realised that you needed to earn this change I so desperately wanted. That one way or another, you had to suffer to be able to make it.' 
 
 He added: 'I thought everything was going to be served on a plate but that's not how it works.' 
 
 Canadian director David Cronenberg, 69, became a saving grace for the actor as he gave him the chance to concentrate on the role of Eric Packer in Cosmopolis.

 Big lineage: Riley's mother is Lisa Marie Presley, who was once married to Michael Jackson. The mother and daughter were seen together at the Commando launch party April 27 in Hollywood ||||| Are they or aren't they?! 
 
 We caught Rob Pattinson driving around his truck with a mystery girl yesterday, and now that we've identified her as Elvis' granddaughter Riley Keough, we have to wonder whether the gorgeous redhead is dating the Twilight hottie? 
 
 This isn't the first time the two have hung out, either! 
 
 The 24-year-old hung with the British hunk at K-Stew's birthday bash at Malo in Los Feliz on April 9. The On The Road actress and Keough co-starred in The Runaways together, and we highly doubt Kristen would have invited Riley to her birthday if they weren't friends, so maybe her pal hanging with her former man is a sign that Robsten is back on?! 
 
 We're thinking Kristen sent Riley to convince Rob to give their relationship yet another go! ||||| Heartbroken Robert Pattinson was weeks from proposing to girlfriend Kristen Stewart when he found out she had been cheating, I can reveal. 
 
 The Twilight hunk has told pals the £5million ­mansion he had bought was to be their home as husband and wife. 
 
 R-Patz, 26, planned to pop the question to Kristen, 22, at the end of the summer – then found out about her fling with film director Rupert Sanders. 
 
 My source said: “Robert hoped to marry Kristen and was making preparations to spring a proposal before she admitted cheating. He had bought the house in Los Angeles to be their home and saw them staying there for a long time. 
 
 “Now Rob is angry – he’s left the mansion and not spoken to her since. They have exchanged heated text messages only.” 
 
 Insiders say 41-year-old Rupert’s marriage to British model and ­actress Liberty Ross, who played Kristen’s mother in Rupert’s Snow White and the Huntsman, is likely to survive the affair. 
 
 Friends of Liberty, 33, say she’s humiliated by the affair ­being made public but does not want to turn her back on her marriage.

 A pal said this week: “Liberty is hurting. But she’s realistic. Things happen and marriage isn’t easy – she just hates the fact her name’s been dragged into all of this. Rupert has apologised profusely and she has accepted his apology. She hopes things get back on track – after all, they have three kids together.” 
 
 Rupert’s father Michael said his son was distraught but the ­marriage is sure to survive. He added: “From what I gather nothing really happened and it is all a lot of fuss about nothing. She is a very pretty girl and when you work that closely with someone for so long, sometimes things happen.” 
 
 Robert and Kristen will be forced to reunite in August to promote the final instalment of the Twilight franchise under their contracts. The stars will promote the movie Breaking Dawn: Part 2 with appearances and interviews. Twilight executives fear Twihard fans will boycott the film now. 
 
 One movie insider said: “This throws a ­spanner in the marketing works. They are the Twilight ­franchise and if that magic is broken then there are ­obvious difficulties.” 
 
 Movie chiefs also fear that the scandal will ­overshadow Kristen’s ­appearance in On The Road. 
 
 Kristen appears ­desperate to save her relationship. She said: “This ­momentary indiscretion has ­jeopardised the most important thing in my life – the person I love and respect the most, Rob. I love him, I love him, 
 
 I’m so sorry.”

– Well, this is awkward: Robert Pattinson was spotted driving to his house with a "mystery girl" Sunday, and she's now been IDed as model/actress Riley Keough. That's notable for three reasons: Keough is the granddaughter of Elvis Presley. She co-starred with Pattinson ex Kristen Stewart in The Runaways. (Pattinson and Stewart most recently split in May.) She's close friends with Stewart, according to the New York Daily News. In fact, she attended Stewart's April birthday party, as did Pattinson. So, are Keough and Pattinson dating? Most outlets seem to be spinning it that way (a source tells the ever-trustworthy Daily Mail the two are "inseparable," while another tells Hollywood Life that Rob "is so happy that he can trust someone again"). But X17 notes that maybe she was actually running interference for Kristen, trying to reunite the Twilight lovers.
