Thandie Newton won`t undergo plastic surgery

London: `Mission Impossible` star Thandie Newton says she will never go under the knife because she doesn`t want cosmetic surgery to affect her ability to express herself.

The 39-year-old actress, who will be turning 40 in November, said she is not worried about the ageing process as her favourite actresses have all shunned the Hollywood trend for plastic surgery, Daily Express reported.

"I`ll be 40 this year, but honestly would not consider surgery; all my beauty icons are women with expressive faces.

"Isabelle Huppert ages so beautifully and gracefully, as have Maggie Smith and Judi Dench. I am struck by their expressive beauty," she said.
