David Beckham's "naked days are over".

The soccer star - who has sons Brooklyn, 12, Romeo, nine, and six-year-old Cruz and six-month-old daughter Harper with wife Victoria - admits he happily walks around his Los Angeles home in his underwear but thinks stripping would be inappropriate because of his little girl.

He said: "My naked days are over. I definitely walk around the house in my underwear. But not naked. With the boys it's not a problem because they're naked all the time but with a little girl now, it is different."

David,36, released his first collection of male bodywear with fashion chain H&M yesterday (01.02.12), and admitted his youngsters get embarrassed when they see him posing in adverts for it.

Unveiling his collection in London, he added: "They say 'Oh my God Daddy - not again'. They were like, 'That's really good, but everyone's gonna see you in your pants.' "

The hunky sportsman also insisted he has never worn an embarrassing pair of pants and doesn't believe in "lucky" undergarments.

Asked if anyone had seen him in bad underwear, he said: "Thankfully not. My parents always provided me with nice underwear.

"I never had a lucky pair of underpants."
