Kylie Minogue wants to challenge Pippa Middleton to a "bum-off".
The Timebomb singer who famously showed off her bottom in tiny gold hot pants in her Spinning Around video released in 2000, admitted she wanted the duel at the forthcoming Jubilee concert.
The 44-year-old performer says she plans on parading her derriere in front of Kate Middleton's sister - who received ample attention at her wedding to Prince William last year because of her shapely buttocks.
Kylie told Alan Carr when asked about a possible contest with the 28-year-old party planner: "I'm going to have to. I'll definitely have to (bend over and) pick something up off the ground."
During her appearance on Alan Carr: Chatty Man, Kylie teased the interviewer about the event held in celebration of Queen Elizabeth's 60 years on the throne.
She said: "I can't tell you too much about the performance, but what I can say is I'm doing a medley."
She also spoke about her sister Dannii's embarrassment when her affair with Simon Cowell was revealed in Tom Bower's biography Sweet Revenge.
She said: "My sister has been through a lot worse - but she's busy with my nephew Ethan who's adorable."
Kylie admitted she had been in talks to be a judge on The Voice but said she'd never join The X Factor panel.
She said: "It's a million per cent no."
