Jennifer Aniston used to love visiting strip clubs.

The 44-year-old actress - who plays stripper Sarah 'Rose' O'Reilly in comedy 'We're the Millers' - admitted she used to frequent lap dancing clubs when she was younger.

She said: ''I've been to enough strip clubs in my twenties as a fan.

''I had an incredible choreographer, Denise Faye, [for the movie] who taught me this beautiful dance and we just perfected it over weeks and weeks.''

Jennifer found her role challenging when she had to perform the routine on set with her colleagues watching.

She told Radar magazine: ''It was the first time walking onto the set with the crew and cameras and having to do the dance. It was a little challenging and I was very intimated. But you've got to go to work. The show must go on!''

The screen beauty adopted a heavy fitness routine and a strict diet to prepare for the part.

Jennifer explained: ''I actually did go to a very scary gym with a scary trainer who made me do crazy things I can't say out loud.

''I got real strict with my diet and I was very persistent with my work-outs.

She was relieved when filming ended and she was able relax and not worry about training.

''When I finished that job I pretty much didn't go to the gym for I don't know how many months. I was over it and like, 'OK, that's enough of that!''

Jennifer is interviewed in this week's Radar Magazine, out on 10th August, available with The Independent newspaper
