SIGOURNEY WEAVER without botox and GHOSBUSTER

The Avatar star, 60, thinks cosmetic procedures are unnatural — and especially silly if you’re an actress.

“I would never have plastic surgery or Botox injections,” she said. “How can you as an actress? They both leave you with such a tight, unreal look.

“It’s something fans and audiences pick up on instantly. Actors’ faces should actually be able to move.”

And Weaver says she doesn’t feel the need to go under the knife — because she finally feels sexier than ever.

“I like my body now, where, in younger days, I could always find fault. I feel I have my curves at last,” she said.

“They may come from age, but I don’t care. I’m just glad they are there.”

Sigourney recently revealed that she’d be open to filming a third Ghostbusters movie.

“I might be in it; I see nothing wrong with being in it, although I don’t think I will have a big part,” she said last month.

“I think Bill Murray has a little more to do with it — he’s a ghost. I have had a couple of calls asking ‘would you read the script’.

“I know that my little son Oscar — who was kidnapped from me [in Ghostbusters 2] — I think he has grown up to be a ghostbuster.
