The British royal and the soccer star - who arrived around 10pm and left at 3am this morning (04.02.12) enjoyed a night out at the exclusive Arts Club, less than two months after they enjoyed a pre-Christmas night out at the same venue. Other guests included David's best friend Dave Gardner and Welsh singer Katherine Jenkins.
David - who is a close friend of both Harry and his brother William - stopped by the club after taping a recording of Jonathan Ross' ITV 1 chat show, where he revealed he and wife Victoria are thinking about expanding their family, which already includes sons Brooklyn, 12, Romeo, nine, and six-year-old Cruz and seven-month-old daughter Harper.
He said: "Harper is seven months now. I can't even look at her without welling up. After having three boys, you just assume that you're going to have another boy, but when we got told she was a little girl, it was amazing.
"We might have one more or two more, you never know. We're not thinking about it yet, but if it happens, great. We're enjoying the kids as it is. It's always a thought.
"I mean, we're busy people and we're enjoying the four kids that we've got already and we're lucky, we're lucky to have four healthy children."
