Clash of the tight buns

Kylie's Jubilee challenge to Pippa

Sizzling buns ... Pippa Middleton and Kylie Minogue

CHEEKY Kylie Minogue has challenged Pippa Middleton to a sizzling battle of the buns at the Diamond Jubilee.

 he 44-year-old Aussie pop princess — who famously flaunted her shapely rear in tiny gold hot pants — will be singing at the concert celebrating the Queen’s 60 years on the throne on Monday.

Also on the guest list is Pippa, 28, whose pert behind stole headlines when she was bridesmaid at sister Kate’s wedding to Prince William last April.
Kylie will be seen revealing her saucy challenge to TV chat host Alan Carr tonight.
Asked by the comic whether she would have a “bum-off” with young pretender Pippa, she said: “I’m going to have to.
“I’ll definitely have to (bend over and) pick something up off the ground.”
Kylie, wearing a hot pink mini-dress, then leaned over and gave a wink to show the Channel 4 audience she is still in excellent shape.
And to help in her battle with Pippa, joker Alan, 35, even gave Kylie a vibrating bottom-toning machine as a gift for her birthday, which fell last Monday.

Yet while she is prepared to tackle the bum challenge, Kylie admits she is nervous about singing in front of the Royal Family.
She said: “I can’t tell you too much about the performance, but what I can say is I’m doing a medley.”

Last week Kylie performed her latest hit Timebomb on The Voice in a cobweb-style dress, which she confides in the chat came from a Soho SEX STORE.
Kylie also speaks on the show about sister Dannii’s embarrassment when Simon Cowell’s affair with her was revealed in Tom Bower’s biography Sweet Revenge — serialised in The Sun.

She said: “My sister has been through a lot worse — but she’s busy with my nephew Ethan who’s adorable.”
Kylie admitted she’d 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.”
