Singer Cyndi Lauper has ruled out more plastic surgery after a doctor botched her tummy tuck in 2006.

The Time After Time singer went under the knife to firm up her abdomen five years ago, but the hit-maker admits she'll never trust a surgeon with her body again after a student in training was forced to complete the risky procedure.

During an appearance on The Wendy Williams Show on Tuesday, she said, "I had a tummy tuck, one time when I was having some other things, issues that I needed (done). It was the worst thing."

"The surgeon was a diva. She left and some student sewed me up. It's not good... I was thin for a second and then, you know, (I gained back the weight again)."
