And now for a highlight reel of the red carpet best of.... Hollywood's finest arrive on the red carpet First look at the Oscar hopefuls arriving on the red carpet ahead of the ceremony. Australian actress Jacki Weaver arrives wearing $2 million worth of diamonds. Quentin Tarantino and Lianne Spiderbaby. Quentin Tarantino and his unusually named lady, Lianne Spiderbaby. Black and gold seems to be the order of the day. Adele! The singer has had a great award season run this year. She departs from her colourful Valentino Couture ensemble at the Grammys today and opts for a beaded floor-length black gown. Still stunning. Francois-Henri Pinault and Salma Hayek. Francois-Henri Pinault and Salma Hayek, who goes for a blinging Baroque look with gold embellishment and black velvet. Nails it, I think. Heidi Klum A plunging neckline can be hard to carry off. And in some cases (sorry Heidi), less is definitely more... Sandra Bullock Sandra Bullock looks effortlessly elegant in her Elie Saab Haute Couture Spring Summer 2013 dress. The sheer embroidered overlay and classic silhouette (with a mini mermaid finish) really works a treat. Kristen Stewart. Kristen Stewart has turned up on crutches with an "unexplained injury." She ditched them to pose on the red carpet in her Reem Acra dress. Kelly Osbourne says she looks "pretty, for her." Assume she's referring to Stewart's usual edgy, sexier look. Her lace dress is a little 'weird mermaid' for us, but hey, she's smiling - sort of - so stranger things... Helen Hunt. Helen Hunt in an "accessible" dress by H&M. H&M! Good on her. Having said that, she does admit to wearing about $700,000 worth of jewels. Talk about mix and match! Jennifer Garner and Ben Affleck. Jennifer Garner, with hubby Ben Affleck, looking magical in magenta Gucci. keeping it sweet and simple, but loving the purple pop and the ruffle at the back gives the dress a bit more punch. Random bit of useless information: apparently Ben Affleck's beard has its own Twitter account (??). Nicole Kidman Who says black has to be boring? Nicole Kidman's black and gold L'Wren Scott body con gown is definitely going to be a talking point tonight. The two-tone sequence is a standout. Love the tousled hair! Amanda Seyfried Now, Amanda Seyfried. The 27-year-old goes for a soft, flowing custom Alexander McQueen dress, complete with Roger Vivier shoes, and Lorraine Schwartz jewels. Straying from the strapless trend so far, her classic halter neckline is a highlight for us. Jennifer Aniston with fiance, Justin Theroux. 11:48am: American sweethearts... George Clooney and Stacy Keibler. Ooh la la. Smoking couple alert. Clooney is in Armani - seemingly a popular choice for tonight. Keibler is in Naeem Khan and she looks like a Grecian goddess. The shape, the detail, the moody metallic - killing it! Jennifer Aniston. Jennifer Aniston in Valentino? Comme ci comme ca. We feel like we've seen this dress a thousand times before. That said, she looks lovely as always. Everyone is underwhelmed. Too safe... If you've got, work it! Perez Hiilton says it how it is: Naomi Watts 11:37am: The amount of excitement around Naomi Watts' Armani Prive dress is palpable. Will it join Gwyneth Paltrow's 2012 Tom Ford cape gown in the Oscars red carpet's hall of fame? Apparently the designer started working on the gown since the Globes. Looks like a winner to us! Charlize Theron. Charlize Theron dazzles in white hot Dior. She had her hair buzz cut for a movie three months ago - this is the regrowth! Effortless glamour and accented beautifully with Harry Winston jewels. Giuliana Rancic calls the 5'11" actress a "freak of nature." She's working the hair like not many people can. Sexy yet simple. Hot, hot, hot! Joseph Gordon-Levitt and Sally Field. Sally Field doing Joseph Gordon-Levitt's bow tie in the car. Cute! Jennifer Hudson Jennifer Hudson wows red carpet watchers in a sleeved Roberto Cavalli Couture number. She's one of a handful of actresses embracing blue so far -- a mini trend tonight? JLaw is getting a mixed reaction on Twitter. Vogue Australia is in love: Others, however disagree. This tweet captures the critics' mood: We think her hair, make up and jewels look incredible. Colour is washing her out a bit though and the tailoring... hmmm. Catherine Zeta Jones Loving Catherine Zeta Jone's dress choice tonight! Fresh off the Zuhair Murad SS13 Couture runway. A flattering silhouette with lots of embellishment at the train. A veritable show-stopper. Anne Hathaway has arrived in Prada. Didn't know what she was wearing until "about three hours ago." Our first impression is 'blah'. One colleague thinks she looks like Miranda from Sex in the City and "not in a good way." Ah, we tend to agree. It's a bit boxy and feels a bit formal-dress for us. Dustin Hoffman with wife, Lisa Hoffman. Dustin Hoffman says his first Oscars was in 1967, "before you were born," he tells Ryan Seacrest. He had a shot of vodka before he came - a little dutch courage for his presenting gig tonight p'raps? Hugh-Jackman Yes, looking this good takes a village ... Les Miserable actor Hugh Jackman lets us in on his last-minute hair fixes on Twitter. Jennifer Lawrence Jennifer Lawrence in her frothy Christian Dior gown. Helena Bonham Carter. Said earlier that I love Helena Bonham Carter, with her shamelessly rebellious concoctions on the red carpet. Have to say though, she's kind of playing it safe here. Love the elegant, fringed train and the sheer, ruched fabric. Witherspoon wears a gorgeous cobalt Louis Vuitton gown (which she apparently picked out with her 13-year-old daughter), while Lawrence (who's nominated for best actress tonight), is in a soft pink Christian Dior creation. Kelly Osborne says,"She looks just like an Oscar nominee should." Top points for the long shimmering necklace too! Not sure about the bottom of the dress, but the black does add a touch of noir drama. Can she walk in it though? there is NO room to move in there, but she gets away with it. Making a baby is his "greatest production," he says. 9:39am: As far as best dressed from Oscars past, Gwyneth's Tom Ford dress from last year was widely agreed to be sensational. But, then I think Helena Bonham Carter's crazy creations are fab too.
