We can't believe how quickly David and Victoria Beckham's four kids are growing up! Of course, they probably can't either...

On Monday afternoon Posh, David, Harper, Romeo, Brooklyn and several pals got together for Cruz's 8th birthday party in London, and while his big day isn't actually until Wednesday, there's no harm in celebrating early!

Plus, mom has been super busy with fashion week events, so we're sure she needed a breather from models and mannequins!
