KYLIE Minogue may not be known for her conservative dressing style but it hasn't stopped the diminutive diva taking a swipe at the sartorial style of her pop predecessor Madonna.

Appearing on the catty US chat show Fashion Police - hosted by Joan Rivers - as part of a promotional tour of the US, Minogue slammed the outfit Madonna wore on stage during her current world tour.

When shown a photo of the 53-year-old singer dressed as a cheerleader, Rivers asked Minogue, who has also been slated for dressing young, for her opinion.

"No. Just no," Minogue groaned.

Rivers, meanwhile, upped the ante, saying: "Madonna, stop it already, you're 108.

"Madonna as a cheerleader? What school does she go to? Our Lady of Osteoporosis? She looks like she flunked 10th grade 48 times."

Minogue, whose "web dress" in her video for Time Bomb left little to the imagination (pictured), was then asked about Madonna flashing her nipple on stage in Rome.

"Was she caught up in the moment? Was it premeditated? Who knows?" Minogue said. "I think it's got people more perplexed than excited by it."

Rivers also asked Minogue about the constant comparisons and competition between herself and Madonna, who she called the "two great pop divas". "Is that because we are the two oldest ones?" Minogue joked.

"Competition. I don't know, but I grew up such a fan of her. I don't even care how we're in the same sentence. It's quite good for me."

Minogue's appearance on the show is part of a US publicity blitz. The Spinning Around singer has also appeared on cable sketch show The Soup eating corn chips from the torso of True Blood hunk Joe Manganiello.
