N-DUBZ had to postpone their appearance at the Forum last night (Wednesday).

The MOBO-winning North London three-piece hip hop and R&B act were due to appear at the University of Hertfordshire Students' Union Bonk club night.

However, Dappy, Tulisa and Fazer had to cancel their sold-out show in Hatfield at short notice due to recording commitments for their new album, the follow up to MOBO winner Uncle B.

Chart-topper Taio Cruz, who was number one a couple of weeks ago with Break Your Heart, filled in for N-Dubz last night and went down a storm.

A statement on the Forum's Facebook site yesterday said: "Due to overrunning recording commitments, N-Dubz's performance tonight has been cancelled by the act's management."

N-Dubz's appearance will be rescheduled for December.
