Mega hit producer Mark Ronson, 33, and his girlfriend, model Daisy Lowe, 19, have split up. Well known in their native England, the attractive couple was often photographed at events and concerts together. Ronson is the brother of Lindsay Lohan’s girlfriend, DJ Samantha Ronson, and is the producer who helped springboard the careers of Amy Winehouse and Lily Allen. He also has a successful music career in his own right and has won several Grammys and a Brit awards. Daisy Lowe is the daughter of Pearl Lowe and rocker Gavin Rossdale, although she didn’t find out her father’s identity until a paternity test revealed the news when she was 15.

The two made their first public appearance together in April of this year. They’re said to have broken up because Ronson is ready to settle down but 14 years younger Lowe isn’t, and has relocated to NY for her career.

Superstar DJ Mark Ronson, the pop guru behind Amy Winehouse and Lily Allen, has split from his girlfriend, Agent Provocateur model Daisy Lowe – with friends blaming the 14-year age gap between them.

The sudden split follows a heated argument four days ago….

But a source said: ‘Mark is not coming to London. He and Daisy had a row over something small which escalated into something rather big.

‘Daisy got very upset and shot at Mark that she was leaving him. He completely surprised her by saying, “Fine, leave.” That was it. They haven’t spoken since the argument.

‘She has said it’s over and that the age difference was a big deal. 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.’

Daisy had moved to New York to pursue her career. The source added: ‘She has quite a few friends in New York and she’s deciding what to do about her future. Her career is going from strength to strength and she’s not sure if she’s ready to leave New York but she is adamant things are over with Mark for the time being.’

The couple were together just last week at Ronson’s 33rd birthday party at Hedsor House in Buckinghamshire.

Daisy was introduced to his family, who had flown over from New York, and told one partygoer: ‘I feel like a Ronson now. I’ve been playing with the nieces and nephews and being polite to Mark’s mum. I’m exhausted.’

But friends say Daisy is reluctant to settle down at such a young age.

A source said: ‘Despite his party-boy image, Mark’s quite serious and just wants to meet the right girl and settle down. That was an issue for Daisy, who is still quite young at heart.

I really liked these two as a couple and they seemed pretty stable. Lowe even made some nice statements in July about Mark’s sister Sam’s relationship, saying that she had met Lindsay Lohan and that they “their relationship is totally genuine. And they’re just so sweet together.” The same could be said of Ronson and Lowe, but it just wasn’t meant to be. We’ll have to see if this is true and if they stay split.

The good news is that Mark Ronson is probably single now.
