Guess that 14 year age difference wasn't working too well for Mark Ronson and his girlfriend Daisy Lowe, because the couple have officially split.
A source tells UK's The Mail, "(Mark) and Daisy had a row over something small which escalated into something rather big. She has said it is over and that the age gap was a very big deal.
"She comes over as being very mature for her years, but at heart she's still a little girl who's not ready to settle down. Daisy still has quite a lot of growing up to do."
Lowe's rep isn't even playing the 'no comment' card. She already released a statement about the split. "Yes, they have split up but we are not making any further comment." He's back on the market girls!
