American pop singer and actress Jessica Simpson admits that she regrets having puffed up her lips.

The reason for the regret is because she looks like "a blowfish".

Simpson was made fun by the US tabloids when it became obvious that she'd had cosmetic work done on her lips last year (07).

But for a change, now it is the singer herself who has admitted that the Restylane lip enhancement was a bad idea.

"My lips look fine the way they are," Contactmusic quoted her as having told People magazine.
