Jude Law is obsessed with manicures.

The 'Anna Karenina' actor - who has children Rafferty, 15, Iris, 11, and Rudy, nine, with ex-wife Sadie Frost, as well as 20-month-old Sophia from a brief relationship with Samantha Burke - hates it when his nails are not neat and tidy and regularly has treatments on his hands.

He said: "I'm obsessed with nail cutting. I've had manicures. I've become a bit obsessed about my nails.

"Playing a sailor in the play 'Anna Christie', I had to shove black make-up under my nails and couldn't scrub it all out for two months - it was a nightmare.

"I'm proud to say that my kids come to me, not their mum, to have their nails cut."

Although Jude takes care of his appearance, he doesn't like it when men appear to have taken too much time to look good.

He added to Britain's Glamour magazine: "Men shouldn't be too groomed. I love the ritual of getting ready for an event, but you can tell when a guy has been standing in front of a mirror for too long.

"Over-trimmed beards, over-styled hair, perfecting a look for hours and pretending it's effortless - do me a favour!

"My routine is shower, aftershave and, until recently, trimming my beard, which I've had for nearly a year for 'Anna Karenina'."
