Daisy Lowe has a new boyfriend.

The British model - who split from 'Doctor Who' actor Matt Smith last November after 18 months of dating - was seen at London nightspot The Box last night (09.05.12) accompanied by a mystery man, before they left to enjoy a private dinner together.

A source told BANG Showbiz: ''Daisy arrived at the event with a guy and they spent most of the evening together. They both looked really happy and left about 10pm, saying they were going for dinner.

''Matt Smith seemed to be the last person on her mind!''

Other guests at the Haagen-Dazs Secret Sensations launch party at The Box included TV personality Donna Air and actress Tamsin Egerton.

The revellers enjoyed cocktails based on the new chocolate fondant and creme brulee Secret Sensations, and got a taste of the new ice creams - with Donna accidentally spilling it all down herself.

Meanwhile, Tamsin seemed to enjoy the entertainment and was particularly taken by the antics of a male contortionist, with onlookers saying she ''couldn't take her eyes off'' him.

When Daisy and Matt split, it was believed to be as a result of their busy work schedules.

A source said at the time: ''This has come as a surprise to everyone. It was thought they'd be together for a really long time because they were so into each other.

''They always seemed so happy together. Matt was besotted with Daisy and she adored him.

''It's really sad that this has happened, but as they're both so in demand at the moment it was really difficult for them to find time together.''
