Jessica Biel says she's always been a tomboy.
The 'Total Recall' actress - who is engaged to Justin Timberlake - plays resistance fighter Melina in the remake of the hit movie which sees her battle with Kate Beckinsale and she admits she wasn't worried about the physical scenes as she's never been very girly.
Speaking about whether she has a reputation as a tough person, she said: ''Maybe not tough, but perhaps tomboy.
''I've always been that kind of person - constantly playing sports and never really into make-up or fashion, until about five years ago.''
The star - who has been in a string of other successful movies including 'The Illusionist' and 'The A-Team' - admits she has to work hard to look good in her films but gets bored of dieting.
She said: ''There are some days when I feel like I can't eat another chicken breast and if I see another piece of broccoli, I swear to God.
''I know I feel better when I see myself on screen and I've been really dedicated, even though it was a pain in the ass. It's there forever and you get one chance.''
