"Extra's" Terri Seymour talked with soccer star David Beckham backstage at "The Ellen Show" - and asked the new dad about his baby daughter, Harper.

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

Does he think she'll be an athlete or a fashionista? Beckham laughed, "Um, well, let's hope she has an athlete's body. But she'll definitely be in fashion."
