Trolls can chuck as much abuse at Sigma as they like - the dance duo feed off it.
Joe Lenzie tells us: "We love when people slag us off. We've had trolls on Facebook and you have to learn not to take it seriously or you'd top yourself."
Some fans of Joe and his Sigma partner Cameron Edwards weren't overly impressed when they worked with Paloma Faith on second chart-topper, Changing.
Joe says: "You get a backlash when you go from the underground to the mainstream. We have nice fans as well. I got a lock of hair with a letter as a Valentine's Day gift from one." Weird.
