She's happily married to producer and director Judd Apatow.
But Leslie Mann has revealed she would love to know exactly what makes her husband tick - by understanding the 'real mechanics' of having sex as a man.
Opening up on what makes her tick alongside The Other Woman co-stars Cameron Diaz and Kate Upton in an interview with Radio 1's Greg James, the 42-year-old actress admitted she would want to get down and dirty if she was transformed into a man for a day.

Revealing all: Leslie Mann has revealed she would love to know exactly what makes her husband tick - by understanding the 'real mechanics' of having sex as a man
She said: 'I would have sex. I would love to know how it operates! Like what the real mechanics feel like! It would be fun to feel the other side, wouldn't it?'
But Kate, 21, had a rather different idea of what she would do if she became a male for 24 hours, joking that she would take great pleasure in 'peeing in a bush'.
She added: 'I mean I would want to pee in a bush. You don't have to squat or wipe, nothing!'
Leslie also revealed she would rather be given $100 in cash than have her husband buy her flowers, a sentiment that co-star Cameron agreed with.

Speaking to Radio 1's Greg James, she added: 'I feel like flowers are a little bit of a waste because they cost like $100. Why not give me something I can use over and over again? Just give me the cash, I would be so excited!'
Cameron chipped in: 'If an envelope showed up at my door with $100, I would be happy!'
Earlier this week, the trio attended The Cinema Society screening of The Other Woman in New York.
Kate had every inch of her famous figure under wraps in an animal print blouse with a black pussybow, along with black trousers and silver pumps.

Wild thing: Kate wore an animal print pussybow blouse with smart trousers and silver pumps, and vampish make-up
The Sports Illustrated model, 21, went for vampish make-up with heavy eyeliner and deep red lipstick, apparently keen to show a more serious side to herself now that she is acting.
Meanwhile Cameron picked a blue mid-length asymmetrical dress which left one shoulder on show.
The 41-year-old actress lengthened her already very long legs in nude court shoes and completed her look by applying a slick of bright pink lipstick and tying her platinum blonde locks into a messy updo.

It was their co-star Leslie Mann who wore the most daring outfit of the three for the event, held at the Big Apple's Paley Center, and co-sponsored by In Style magazine and Bobbi Brown.
The Knocked Up star, who is married to Judd Apatow, sported a racy black and white striped peplum corset top.
Leslie, 42, teamed it with cropped black trousers and striking platform shoes with gold spikes on them.
The movie follows three women - Carly, Kate and Amber - who team up to exact revenge after realising they are all seeing the same man.
The Other Woman will be released in the US on April 25 and came out in the UK on April 23.
