Aussie pop star Kylie Minogue has thrown down the gauntlet to Pippa Middleton, challenging her to a 'battle of the butts' at Queen Elizabeth II's Diamond Jubilee.

The singer rejuvenated her career in 2000 when she flashed her backside while gyrating in a pair of skimpy gold hot pants in the video for her track Spinning Around.

The film caused a sensation and led to Minogue regularly topping light-hearted 'best butt' lists ever since - but she faces fierce competition from Middleton, who caused an online storm with her shapely posterior at her sister Catherine's marriage to Britain's Prince William last year.

Minogue will be performing at the Diamond Jubilee Concert in London on Monday, where Middleton is also expected to be in attendance - and the singer has challenged her rival to a contest to see who has the best rear.

In an interview on U.K. talk show Alan Carr: Chatty Man, to be aired on Friday, Minogue says, "I'm going to have to (challenge her). I'll definitely have to (bend over and) pick something up off the ground."
