Sexy actress Sarah Michelle Geller will be 30 when she plays adolescent Sabrina in the movie adaptation of Sabrina The Teenage Witch.

The Buffy The Vampire Slayer star, 27, has beaten Britney Spears and the TV show's star Melissa Joan Hart to the part, which begins filming in late 2006.

A source says, "A few names have been mentioned, including Britney Spears, but recently she's lost that teenage innocence tag.

"Geller might be a bit older but she still looks fantastic."
