Celebrities wading into political debate is never a good idea. Sharon Stone found out as much when she commented on "karma" causing the recent earthquake in China. In retaliation, the country's largest cinema chain banned screenings of all of her films. While Chinese cinema-goers are lamenting the loss of Basic Instinct 2, Michael Jackson has been going to increasingly elaborate lengths to avoid being spotted in public. Attending a mixed martial arts game in a wheelchair, sunglasses and a coat around his face, it seems the King of Pop might need a few lessons in keeping things inconspicuous.

Sharon Stone to... Sienna Miller - Born and raised in Pennsylvania, Sharon will surely have been a bit miffed after hearing Sienna Miller's outburst about the state's second largest city Pittsburgh. While filming in the area, Sienna dubbed it "S***sburgh", adding to an interviewer: "Will you pity me when you're back in your funky New York apartment and I'm still here?" The furore it caused even forced her to apologise to the city's mayor.

Sienna Miller to... Kelly Osbourne - If outrage from Pennsylvanians weren't enough, Sienna has also had to take flack from Kelly Osbourne. Ozzy's daughter launched a scathing attack on Jude Law's ex after growing tired of her complaining about paparazzi intrusion into her life. "Don't be famous if you don't want it," Kelly remarked. "Don't spill your beans to everyone, and don't be famous if you don't want some attention."

Kelly Osbourne to... Beth Ditto - Having amassed a group of celebrity friends including Kate Moss and Kimberley Stewart, the latest number to go into Kelly's phone book is Beth Ditto's. The Gossip singer hobnobbed with Kelly backstage at the Brits and has no doubt been taking tips from her on surviving the frantic celeb lifestyle. Ditto has also managed to form an "odd couple" partnership with a scarecrow-like indie icon.

Beth Ditto to... Jarvis Cocker - The Pulp indie icon teamed up with Ditto for the single 'Temptation' earlier in the year, with all proceeds going to homeless charity Shelter. After debuting the song at the 2007 NME Awards, Jarvis was keen to big up the duet: "It has taken a full twelve months for the world to be ready for this track - I hope you enjoy it as much as we enjoyed performing it."

Jarvis Cocker to... Michael Jackson - Jarvis memorably made a name for himself by invading the stage during Michael Jackson's 1996 Brit Awards set. Cocker explained his spur of the moment protest, saying: "My actions were a form of protest at the way Michael Jackson sees himself as some kind of Christ-like figure with the power of healing." The result sent Pulp's record sales surging and a £30,000 Madame Tussaud's waxwork quickly put on display.
