Model Daisy Lowe, 19, glams up for night out with new man Mark Ronson, 32

Model and ingenue Daisy Lowe was seen out with super-producer Mark Ronson for the first time last night, as the couple announced their new coupling on the London social scene.

And maybe mindful of the 13-year age gap between the pair, Daisy, 19, ditched her usual sexy rock chick style for a more sophisticated, glamorous look for the night out with new boyfriend Mark, 32.

The hot new couple partied until 3am, kicking off with the launch party of the Belvedere Jagger dagger at Automat, before moving onto Bungalow 8.

They then moved onto the Notting Hill Arts Club before retiring to Mark's hotel in Liverpool Street.

Mark was formerly engaged to Quincy Jones' daughter, actress and singer Rashida Jones in 2003.

And he dated American artist Cosi Theodoli-Braschi for three years until the couple parted ways in early February 2008.

Daisy has dated William Cameron, the guitarist and singer for indie band Blondelle.

In 2004, a DNA test revealed that her biological father was not her mother's first husband, as she had previously believed, but Bush frontman Gavin Rossdale.

Mark Ronson gets engaged to his Agent Provocateur model and actress girlfriend Josephine de La Baume

Mark Ronson has announced he's got engaged to his girlfriend, model and actress Josephine de La Baume.

Musician and producer Mark, 35, has been dating the 26-year-old French beauty since 2009 and even got her to star in the video for his recent single The Bike Song.   

Rumours that Mark had gone down on one knee have been swirling since the waifish blonde was pictured wearing a ring on her wedding finger in Paris last month.

Ronson was previously engaged to actress Rashida Jones, daughter of music legend Quincy Jones, in 2003 and also briefly dated Daisy Lowe in 2008. 

Ronson’s engagement follows a spate of celebrity engagements of late.
