On Wednesday, the two pop stars engaged in a playful Twitter exchange about Rihanna's recent trip to a Miami strip club, King of Diamonds Gentlemen's Club. Rihanna had posted pictures of herself online, to which Katy responded: "Ermm...I was in LA Saturday night...Should I be proud or offended I wasn't invited @rihanna #WHOISTHISDOPPLEGANGER" Rihanna shot back a chirpy: '@katyperry errm I wasn't! Lol! #miaminights howeverrrrr....I'll still let you spank me!' Perry left the possibility open of spending more time together, replying: "Don't worry @rihanna I'll make it up to you at Barclays... Or more like let you make it up to me... Hehehe @rihanna. Rihanna visited the Florida strip club to celebrate "weed day" on April 20 (4/20 on the American calendar), excitedly tweeting to her fans about what a good time she was having. In February, it was reported that Perry's disapproval at the October 2012 reconciliation between Rihanna and Chris Brown had caused the two former friends to fall out. At the Grammy awards that month, Perry was reported to have requested she be seated nowhere near the couple. The gal pals were last seen hanging out together at the MTV Video Music Awards in September 2012.
