N-Dubz rapper Dappy has been forced to apologise for sending a death threat to a Radio 1 listener.
The 22-year-old sent a series of abusive texts to a mum who texted the radio station criticising him and N-Dubz.
Mum-of-one Chloe called NDubz "losers" and Dappy "vile" in texts to The Chris Moyles Show on Tuesday.
