Dappy from N-Dubz, a man more irritating and less talented than every single member of Blazin' Squad rolled into one, has been caught on CCTV snorting the now illegal high mephedrone - despite claiming he'd been off drugs for years. He's now come out and confessed his sins and promised never to get caught do it again...

The footage was shot last month so - technically - the drug was legal when Dappy dragged himself into the back office of a nightclub at 5am and snorted it through a rolled-up fiver.

However, he's still been forced to come out and given a remorseful apology for his actions, urging his fans (who are probably all on the stuff anyway) not to take it either.

The singer (is that what we call him?) began his apology with this amazing line...

"I said recently that I hadn't touched serious drugs for years and maybe that wasn't completely true."

Yeah, maybe that wasn't completely true. Perhaps that was a lie. Just possibly...

"I was taking meow meow. I was on a night out with mates and it got a bit rowdy. Meow meow was legal and lots of my mates were taking it too. I know this drug has now been made illegal and would not endorse any of our fans taking it."

Maybe we should give the guy a break, all his friends were doing it - imagine how uncool he would've looked if he hadn't joined in - it was just peer pressure.

"I now want people to realise how dangerous mephedrone and similar drugs can be. It can ruin lives. I'd want any of our fans to stay well clear. I've learned my lesson and hope others will too."

That's very big of you, Dappy. But we'll believe that when we see it...

According to someone who imagined the incident their head claims to have been there, Dappy came out afterwards "grinning stupidly" and then left soon after, complaining that he was "feeling unwell".
