Guest-hosting The View on Friday, Kate Gosselin barely flinched when Whoopi Goldberg et al asked her to clarify what work she's had done to her body and face.

"I've had a tummy tuck — we all know that," Gosselin, 35 says.

She hedges when asked about her boobs. "Why is it so fascinating? I got a good bra!" (A pal tells Us Gosselin had breast enhancement surgery in March 2009, with bodyguard Steve Neild giving her advice.)

Botox? "Absolutely not," she claims.

Still, despite her denials, an insider confirms to Us the reality star recently had a botched Botox job — and the experts agree. Observing a June 21 snapshot of Gosselin, dermatologist Kenneth Beer told Us Weekly that Gosselin's "outer brow is too peaked, which gives her a devilish appearance…This is likely a bad injection technique with poor placement."

Thank You!
