Australia's pop diva Kylie Minogue has poked fun at Madonna for the cheerleader outfit the 53-year-old has worn on stage during her world tour.
Minogue, 44 - who herself wears a revealing black web dress in the music video for her latest single Timebomb - was apparently taking a swipe at Madonna for dressing too young.
Minogue's comment, which came after some prompting, occurred on Friday when she appeared on Fashion Police, the catty American chat show co-hosted by comedienne Joan Rivers and Kelly Osbourne.
Rivers showed a picture of Madonna dressed as a cheerleader and asked Minogue for her opinion.
"No - just no," Minogue said, groaning.
Rivers, picking up the signal, said: "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."
Rivers then asked Minogue's opinion about an incident this month in which Madonna flashed a nipple at a concert 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."
The two stars have a history of rivalry. In a 2000 awards show Madonna wore a T-shirt emblazoned with the words "Kylie Minogue" and, in 2010, Minogue put out publicity shots of herself in a Jean-Paul Gaultier conical bra of the kind Madonna made famous in her 1990 Blonde Ambition days.
Rivers referred to the competition between "the two great pop divas".
"Competition. I don't know, but I grew up such a fan of her," Minogue said. "I don't even care how we're in the same sentence. It's quite good for me."
Minogue is in the United States to promote Timebomb, which marks her 25 years in the music industry.
