JANE FONDA’s startling confessions – she has nothing to hide NOW.

The Barbarella star, who will turn 73 in December, has admitted to going under the knife.

 "I recently had plastic surgery," Jane admitted.

"It was a hard decision to make and I decided if I’m gonna do it, I’m gonna tell the truth. I’m writing a book about aging; I can’t write that book and not say I’ve had plastic surgery.

"I just decided it was for me; I didn’t want to have bags under my eyes that made me look tired.

"I have a new hip. I have a new knee, and I’m going to soon be bionic," Jane wisecracked.

And Jane’s other health secrets other than invasive surgery?

"I’m careful about what I eat, I stay active, walk a lot.

"I have good genes."
