Katy B tells the latest issue of Q Magazine that her backing band are "like the mafia".

The 'Lights On' singer admits her band step in when she gets amorous boys approaching her during her live gigs.

The 22-year-old reveals: "When I was playing clubs it would be all sweaty boys on ecstasy at the font calling my name. So I'd be like, 'OK, I've gotta go now, find my mates,' but my band are all like my bl***y brothers, they're like the mafia around me, so I'm alright."

'Lights On' hitmaker Katy also acknowledges being hot is now part of her image since she has "scrubbed up," but doesn't want people to only listen to her just because of the way she looks.

The dubstep singer said: "I've scrubbed up a bit, I used to go on stage in an old jumper, but I don't want someone to like my music because they feel attracted to me. Or, like I'm hot or something, that's not what I'm about at all. I don't care."
