Singer Robbie Williams keeps fit with sex!

London: British singer Robbie Williams says he practises sex to keep himself slim and fit. The "Love Light" singer, who has famously battled with his weight throughout his career insists his new toned physique is because of sex with fiancee Ayda Field, reports femalefirst.co.uk.

When asked about his perfect shape body, Williams said: "You`re talking about sex now. Yes we do it, we do it, we really do it!" However, the singer also runs everyday to stay in shape. "I`ve been running six or seven miles (10-11 km) a day, playing a couple of 90-minute games a week, so I am knackered. I don`t think I`ve lost weight but I have toned up. It`s been a good process and it`s been great to have something to aim for," Williams added. IANS
