British singer Jessie J doesn't know how to use her new Mercedes SLK because she is used to driving a Ford Ka. The Do It Like A Dude hitmaker was given one of the top-of-the-range cars by her record company but is having trouble with the £44,000 vehicle. She told British newspaper The Sun: "I gave my Ka to my dad. I've now got a brand new Mercedes SLK, but the only thing is I can't drive it. My Ka was like a go-kart, but with this I'm a mess. I don't know how to use the radio. "I try to indicate and I spray water at people and I'm not a fan of the heated seat because it feels like you've wet yourself."
