Actress Jennifer Aniston believes in ageing gracefully and she's glad her beau Justin Theroux agrees. She says he would "put a gun" to her head if she ever went under the knife or took injections to look younger.

`I think, what I have been witness to, is seeing women trying to stay ageless with what they are doing to themselves,` she said in an interview, reports people.com.

`I am grateful to learn from their mistakes, because I am not injecting (anything) into my face. I see them and my heart breaks. I think, 'Oh God, if you only know how much older you look.' They are trying to stop the clock and all you can see is an insecure person who won't let themselves just age.

"I also have a fiance who will put a gun to my head if I touch my face in any way,` she added.

The 45-year-old thus plans to age naturally.

`I also understand that age is kind of awesome. I am fortunate enough to know women like Gloria Steinem, who I think is one of the most stunning women on the planet, and doesn't touch her face.

"Diane Keaton, Annette Bening, all of these fabulous fearless women who are flawless, they embrace it. You know to each their own, I don't judge it if you do it, but sometimes I wish I could beg the people I know, who I am very near and dear to, to not touch their face,` she said.
