Ed Sheeran, Tulisa Contostavlos Celebrate Dappy's Number One

Ed Sheeran and Tulisa Contostavlos joined Dappy to celebrate the N-Dubz star's number one single 'No Regrets' in London last night (September 25).

Taking place just hours after the rapper's debut song topped the official UK singles countdown, the party also attracted Dionne Bromfield and Tinchy Stryder.

Dappy posed for pictures with his N-Dubz bandmates Contostavlos and Fazer, who recently confirmed that they are dating.

The trio are currently working on their own projects away from the group, with Contostavlos appearing as a judge on The X Factor.

Other guests at Movida included Dappy's mum Zoi Agorou and girl-group Parade.

Meanwhile, as Dappy topped the UK singles chart, Kasabian went straight in at number one on the album chart with their latest effort, 'Velociraptor!'.
