"Charmer" was first teased earlier this week in an announcement video that confirmed Tulisa, Dappy and Fazer reunion after an 11-year hiatus.

The new song, produced by Rymez, follows the trio's 2010 third album Love.Live.Life.

As well as returning with a new single N-Dubz will head out on a UK arena tour in November with support from Wes Nelson. They'll play The O2 in London on 17 November. They've also announced some extra dates due to demand, which includes a second London show at The O2 on 23 November. Tickets for the new shows will go on sale Monday (23 May).

N-Dubz's "Charmer" single is out now.
