Kelly Osbourne has vowed never to wed in Las Vegas - because she has more "class" than fellow rock offspring Peaches Geldof.

Sir Bob Geldof's wildchild daughter married rocker Max Drummey in the U.S. gambling mecca in September following a whirlwind romance.

And it was rumoured Osbourne would follow suit and marry her model fiance Luke Worrell in a similar Sin City union.

But Osbourne has slammed the reports - insisting she would never even consider exchanging vows in Las Vegas.

She says, "I wouldn't get married in Vegas - I have a touch of class, thank you.

"I feel sorry for Peaches - I feel like it was such an attention thing."
