Jessica Simpson regrets plumping up her lips last year because she looked like "a blowfish".

The U.S. tabloids poked fun at the singer/actress when it became clear she'd had cosmetic work done on her lips and now Simpson herself admits the Restylane lip enhancement was a bad idea.

She tells People magazine, "My lips look fine the way they are."

Jessica’s mouth is now back to normal, as the effects of Restylane typically only last six months.
