(Cover) - EN Showbiz - David Beckham says he is still in disbelief that he finally has a daughter.

The soccer player and his wife Victoria welcomed baby Harper Seven into the world in July after being parents to three boys.

He spoke to Extra! backstage at The Ellen Show where he dished about his parenting duties with his new bundle of joy.

"Every time I change her nappy, her diaper, I just think, Oh my God! I can't believe I've got a girl," David gushed.

When asked if he thought the two-month-old would be athletic like him or a fashionista like her mother, David was diplomatic in his answer.

"Well let's hope she has an athlete's body. But she'll definitely be in fashion," he said. "And with three brothers running around and kicking footballs at her she'll definitely be athletic."

David also revealed that his family are close friends with pop star Justin Bieber and the Baby singer has sent his sons signed guitars and even had a birthday treat for their middle son.

"It was Romeo's birthday last week and we took him down to the studio to see him," the proud father said. "But if he wants to perform for the boys I'll give him [football] lessons any day of the week."

David has a new underwear line coming out in February and says that the advertising campaign is going to be even better than the famous half-naked one he did for Armani.

"The pictures are great. They are better. Of course you have to step it up a little bit. They are my own underwear so of course they are going to be better," he said modestly. (C) Cover Media
