“I would adopt him any day. Forget the babies, I’ll have him. I’m such a dirty old cow.” — Sharon Osbourne, 54, on Brad Pitt, 43, at the Elton John AIDS Foundation Benefit on Tuesday.

Kelly Osbourne walked the red carpet earlier today in central London to support actor pal Kevin Zegers (pictured below) at the world premiere screening of his new film, It’s a Boy Girl Thing. The screening was held at the Odeon West End and was in support of the Elton John AIDS Foundation.

Kelly, 22, was accompanied by her and mom, Sharon Osbourne, 54. British singer Geri Halliwell (you do remember the Spice Girls, don’t you?) also showed up looking pretty classy with George Michael’s long-time partner Kenny Goss. It’s a Boy Girl Thing opens in theaters in the UK the day after Christmas, Dec. 26, and also co-stars Samaire Armstrong (The O.C.).
