Jennifer Aniston likes men to wear "tighty-whities".

The 40-year-old actress — who is divorced from Brad Pitt and is rumoured to be dating Gerard Butler — hates it when guys don baggy underwear, preferring to see them in skintight briefs.

She said: "I like tighty-whities on a man. Not boxers. I don't like boxers. Boxer briefs."

Jennifer is just as adamant about the clothing she likes to see on women, and is even considering bringing out a fashion range to make her chosen style more readily available.

She explained: "I'd love to do a bathing suit line. I always have a hard time finding a good bathing suit and so I usually end up tailoring bathing suits. You should be able to mix and match your bottoms.

"For men I like surf shorts. I think that's beautiful."

Jennifer can soon be seen on the big screen in 'Love Happens' — about a widower who writes a book about coping with grief which becomes a bestseller — in which she has a terrible date with co-star Aaron Eckhart.

She is pleased to admit she has never had an awful date in real life, but has had some she hasn't enjoyed.

Jennifer explained: "I have to say that luckily I haven't had one. Nothing's gone beyond just being bored. It's that thing where you just want to go home and they're like: 'So, do you want to go somewhere afterwards?' And it's like: 'No.'"
