Osbourne planning Las Vegas wedding?

Kelly Osbourne is reportedly planning to marry boyfriend Luke Worrall in an Elvis-themed ceremony in Las Vegas.

The Radio 1 presenter has voiced her desire not to marry Worrall in the conventional way.

"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," a friend told Star magazine.

"They are even toying with the idea of an Elvis-themed ceremony. They share the same sense of humour and unconventional streak, so they wanted to celebrate their love for each other with something different and memorable."

The pair sparked engagement rumours after Osbourne was spotted wearing an engagement ring last September.
