Madonna younger menMadonna's brother Christopher Ciccone is a little weirded out by his sister's taste for younger men.

"I guess if she continues to date all these much younger guys, it could start to look creepy," Christopher tells RadarOnline.com, referencing Madonna's new 24-year-old French beau Brahim Zaibat.

Radar previously reported that Madonna, who turned 52 last August, is eight years older than Zaibat's mother. Before Zaibat, Madonna was linked to 24-year-old Brazilian model Jesus Luz.

"She certainly isn't following societal values, but then again my sister never has and probably never will either," Christopher says.
