Jack Osbourne is former TFI Friday star's 'honorary brother'

Former TFI Friday star Catalina Guiardo has adopted Ozzy Osbourne's 16-year-old son Jack as an honorary younger brother.

Rumours had swept Hollywood about the relationship but Catalina says they're just good friends.

She says she's been advising Jack on the pitfalls of TV stardom after he found fame on The Osbournes.

She told the Sunday Mirror: "He is very cool, and he's more intelligent than most 30-year-old men in Los Angeles.

"He's just starting out having all this TV fame and because I've had it in London, it's nice for him to talk to me about it. I can tell him about the pitfalls, the phoney friends, the hangers-on who won't be around when your TV show ends.

"We met three months ago at an LA bar which promotes local rock bands and just started talking. Because we're both British we hit it off and have become good friends. He's a very sweet kid, fun to hang out with, and we share the same sense of humour."
