Rob Kardashian, Adrienne Bailon

Remember how your mother told you tattoos were permanent?

Adrienne Bailon is learning that the hard way. The former Cheetah Girl said on her new daytime talk show, The Real, that she regrets getting ex-boyfriend Rob Kardashian's name tattooed on her butt, according to US Magazine.

"I've gotten pretty bad tattoos before," Bailon said. "Everybody knows I have the ratchet-iest booty tattoo of an ex-boyfriend. I don't know what I was thinking."

The 29-year-old said she was working to get the tattoo removed via laser tattoo removal. "It does not feel good. You could smell your flesh burning. And it's my a-- flesh burning!"

Bailon and Kardashian, who has Bailon's name tattoed on his left ribcage, dated from 2007 to 2009.
