Jennifer Aniston ''commends all strippers''.

The 44-year-old actress plays a stripper in her new movie 'We're The Millers' and admitted as a result she has a new respect for those in the profession because she hated taking her clothes off in front of the cast and crew of the film.

Speaking on 'The Talk', she said: ''I did stupid things. I layered my underwear, I had three thongs...three bras. I mean if something's gonna fly out at that point, three of 'em aren't gonna stop it. It's not easy to get naked in front of other people that you don't want to be naked in front of, so I commend all you strippers!''

Jennifer also made sure she was in excellent shape as she prepared to show off her body in the movie but found working out difficult as she had knee surgery two months before filming began.

She explained: ''I actually had also just come out, about two months prior, [of] having knee surgery. I was having to do these intense squats and, you know...the moves that you do when you're stripping.

''It was pretty intense - I had a knee brace on the whole time until I shot it.

''I had a trainer who was an animal. I was doing things [where] I was like, 'I don't want to do that ever again.' ''
