Demi Moore and Amanda Bynes: Butts-a-Poppin'!

Spring has sprung, and so will you when you leave your house and have a look at the revealing outfits being worn on the beach and in the street.

Though Mr Skin realizes that sometimes leaving your home or office is not an option, so he's kindly taken it upon himself to bring the warm weather heinie to you!

All-grown-up (and out) former Nickelodeon star Amanda Bynes stopped off after her workout to pick up some magazines and got cheeky when she let her lower butt peek out of her short shorts. It's no naked Amanda Bynes, but it'll do nicely.

Ashton Kutcher may be married to Demi Moore, but there's no need to be jealous when the very generous Ash is hitting Twitter to share pictures of his sexy wife's hot ass in a tight white bikini. According to CelebNewsWire, Kutcher tweeted:

watching my wife steam my suit while wearing a bikini. I love God!
