Braving the cold, wintery gales sweeping around Leicester Square last night, some of the legion of stars appearing in the upcoming star-studded love-a-thon rom-com stepped onto the ice cold red carpet last night.
Ashton Kutcher and Demi Moore made an appearance (and you can follow a blurry photo diary of what fun they had on Ashton's Twitter pagehere. If you want to, that is), as did the ever-delightful Jessica Alba - though she probably regretted wearing a tiny little green dress, but still, top marks for bravery.
Topher Grace (Yep, him off 'That '70s Show') rocked up, as did Emma Roberts (Julia's niece, and star of Hotel For Dogs) besides the King Of Rom-Comedy, Garry Marshall himself.
Check out some pictures and a video report of the event below.
