Mark Ronson used to wear his mother's clothes

Mark Ronson has confessed to wearing his mother's clothes when he was younger.

The producer - who has worked with the likes of Lily Allen, Amy Winehouse and Christina Aguilera, admits he used to raid his mom's wardrobe looking for 70s-style flowery outfits.

He said: "When I was 14 I began playing in my first band, which had an early 70s Sly And The Family Stone-type funk influence, so I'd raid my mum's wardrobe looking for flowery print shirts and psychedelic-looking overcoats.

"I even had my hair chopped in a bowl cut like The Stone Roses."

That star, however, insists his cross-dressing was encouraged by his his writer mum, Ann Dexter-Jones.

He said: "When I was 13 I put a blond streak in my hair, then it grew out. My mum encouraged me to put it in for my Bar Mitzvah because she didn't want me looking like all the other kids."

A Bar Mitzvah is a Jewish coming-of age ceremony held for boys when they reach their teenage years.

Meanwhile, Ronson has insisted he will not be spinning the tunes at Suri Cruise's 2nd birthday later this year.

The 'Valerie' star told Ryan Seacrest on his KIIS FM radio show yesterday, "That's the most ridiculous thing I've ever heard.

"I saw the reports online. I did DJ at Tom Cruise and Katie Holmes' wedding - so I guess somebody thought it would have been a funny story to make up.

"Could you imagine the inappropriateness of having someone playing really loud music at a two-year-old's party?"

When asked if he would DJ at the tot's birthday party - if he was given the opportunity, he said: "I don't think so. No offense - I'm just kinda busy making records. I haven't been DJing Bar Mitzvahs, weddings or birthdays lately."
