Raunchy rocker Pink thrilled fans by flashing her underwear on The Ellen Degeneres Show this week, but she isn’t the only celebrity to have stripped on the daytime talk show.

We don’t know what it is about the playful host which makes her guests want to strip down, but Celebuzz has noticed that it’s a regular occurrence on her set.

From Pamela Anderson to Mario Lopez and Ashton Kutcher to Sheryl Crow, Hollywood’s hottest are lining up to take it off on national TV.

So what makes them want to peel back the layers?

Kutcher is the only celebrity to bare all. His manhood had to be pixelated out for his skit. The stark image was being used to promote his show Two and a Half Men.

While it seemed appropriate for Lopez — who was promoting his new line of underwear — to show off his briefs, for others there wasn’t such a good reason.

As former Baywatch babe Anderson, she simply couldn’t wait to strut her stuff in a teeny tiny bikini. Why? To play volleyball with Olympians Misty May-Treanor and Kerri Walsh.

Meanwhile, poor Alex Pettyfer fell for DeGeneres’ prank when he appeared on the show, stripping down because the host told him all first-timers had to take their shirt soff.
