Kylie Minogue insists her "glory days are over" when it comes to her butt.

The 44-year-old star is famed for her petite frame and pert derrière, which is widely admired. Kylie has joked that she has competition from the likes of Kim Kardashian and Pippa Middleton these days.

"Ooooh I don't know! I think I'd come third. I don't know who would come first or second. I'm hanging in there but my glory days are over," she quipped in an interview with the UK edition of OK! magazine.

"My bum is still in the news though - I was on The Wendy Williams Show in New York last week and she said my bum was voted number one. I was embarrassed because I think she was referring to an old poll!"

Kylie is a gay icon and is renowned for her dazzling live shows. The star has revealed the most extravagant thing she's ever done on stage.

"Where do I start?! I guess being carried into G-A-Y in a bath was pretty gay! That was flamboyant. Arriving at one of my shows on a ship anchor... The Sydney Olympics, being brought in on a flip-flop..." she laughed.
