Kelly Osbourne is set to follow in the footsteps of fellow rock offspring Peaches Geldof by wedding her model boyfriend Luke Worrell in Las Vegas next year, according to reports.

The pair allegedly became engaged in September after a whirlwind romance.

And they're now eyeing a quirky union in Sin City rather than a traditional church affair, according to Britain's Star magazine.

An insider tells the publication, "They want their wedding to be fun rather than a big, solemn occasion, which is why they are thinking something Vegas-style would work best. They are even toying with the idea of an Elvis Presley-themed ceremony."

Rumors of an engagement have circulated since Osbourne was photographed wearing a diamond ring on her wedding finger.

But the reality TV star later denied the reports, insisting she and her 18-year-old beau were too young to settle down.

A representative for Osbourne has refused to comment on the reports.
