Ronson splits from girlfriend Lowe

Music producer Mark Ronson and underwear model Daisy Lowe have ended their relationship.

The couple reportedly had a series of rows in New York last week, causing 19-year-old Lowe to break up with Ronson, 35.

A source told the Daily Mail that commitment issues may have been part of the reason why Lowe, due to model at London Fashion Week, decided to end the romance.

"She comes over as being very mature for her years and incredibly sophisticated but at heart she's still a little girl who's not ready to settle down," said the insider.

The pair recently announced plans to sing together at Lowe's mother's wedding in December.
