One Direction taking Zumba classes to stay fit?

Boyband One Direction have reportedly taken up Zumba classes to get in shape for their live shows. The group, Louis Tomlinson, Liam Payne, Harry Styles, Zayn Malik and Niall Horan, begin their world tour at London's O2 Arena on February 23 and so have joined the dance and fitness class in a bid to get fit, reported Sun online. "The lads are not natural movers so them dancing to Latin music is a sight to behold. But they know it's good for fitness so they're putting in the graft," a source said. They have also been warned off late night partying, drinking and smoking by their management to ensure they are in peak physical condition for the 100 date global tour, which will last for ten months.
