Troubled singer Amy Winehouse has been seen spending the night with producer Mark Ronson according to newspaper reports.

The News of the World claims the former Brit School pupil, whose husband Blake Fielder-Civill is in jail, spent the night with Ronson after a late-night studio recording session.

Amy and Mark worked together on last year's number two hit, Valerie, a cover of the Zutons' hit.

Ronson has had a string of high-profile showbiz relationships and was engaged to US television star Rashida Jones in 2003.

Winehouse recently swapped her famous black beehive for blonde hair and an old scarf, leading Carole Malone to liken her to Hilda Ogden in her column for the Sunday paper.
