David Beckham's son wants to call sister Justine Beckham

David Beckham's son Romeo wants to name his new sister "Justine Bieber Beckham".

The soccer superstar and his wife Victoria are expecting their fourth child - a confirmed daughter - later this year and their middle son is desperate to name the new arrival after his favourite pop star Justin Bieber.

During an appearance on 'Jimmy Kimmel Live!', David said: "When we got told it was a boy, Romeo said, 'How about Justin Bieber as a name? Justin Bieber Beckham?'

"So now we know it's a girl, he said, 'Well, how about Justine Bieber Beckham?' "

David says Romeo, eight, and his brothers, Brooklyn, 12, and Cruz, six, are huge fans of the 17-year-old singer and the youngest two boys met Justin after one of his concerts.

Speaking about their love of the 'Baby' hitmaker, the 35-year-old sportsman said: "The funny thing is, I was on the way to school drop off the other day and my youngest said, 'Do you think we could have a play date with Justin Bieber?' I said, 'I think he's a little bit busy.' "

The Los Angeles Galaxy player also revealed he and Victoria, 36, are thrilled they are having a girl, because the former Spice Girl was worried there was going to be "another penis" in the house after their first scan.

He revealed: "We've got three beautiful boys and we're ecstatic to have another one on the way but when we first found out, we went for the scan and they said, 'Oh, it's a boy,' and we were like 'great' but Victoria was like, 'Ahh, another penis in the house.'

"She thinks there's too many in the house already. So then we went back for the next scan and they said, 'Oh, we think it's a girl.' So we were like, 'Oh, OK, well, that's amazing.'

"And then on the final scan they said it's definitely a girl so, yeah, it's incredible."
