You'd think Ricky Martin would be pretty satisfied with his physique, but he has one major complaint: his bottom!

According to tabloid The Star, Ricky decided his butt is too flat and he's turned to the pros for help.

He's doing everything from rock climbing to special exercises to boost his behind. (Maybe this is a job for Suzanne Somers and her Butt Master!)

It's a big secret, but the Livin' la Vida Loca hunk has even resorted to wearing specially designed buttocks pads sewn into his jeans!

Of course he's considered surgical butt implants, but the bottom line is the idea scares him. So for now, it's exercise and padding.
