DS caught up with indie-pop duo Ting Tings after their performance at Radio 1's Big Weekend on Saturday.

Drummer Jules De Martino told DS that the stage was "like a fitness centre", saying: "We were working so hard in the heat and sweating so much!"

Meanwhile, singer Katie White was worried the heat would affect her appearance, saying: "We're taking fans with us next time and I want a humidifier because I get frizzy hair."
