British DJ duo Groove Armada were terrified ex-Sugababes singer Mutya Buena would be "a little monster" ahead of their recent duet together. The SUPERSTYLIN' group, which comprises of TOM FINDLAY and ANDY CATO, recently worked on the electro pop single SONG 4 MUTYA (OUT OF CONTROL) with the tiny singer. Findlay says, "I thought she would be a little monster. Mutya came into the studio and she was nice. "You forget how young she is - she's 21 - so she has her little mobile phone and is on it to her little mates talking about getting the right colour of hair dye. And in the middle of this you're trying to write a track. "She has her own opinion and she can really sing - she's a very good performer."
