David Beckham brought his sons, Romeo, Cruz, and Brooklyn, along to meet with Olympics security guards today in London. The foursome posed for photo then moved on to the BMX finals where they mingled with fans in the crowd. The Olympics have been a full-blown family affair for the Beckhams. After David drove the flame to the opening ceremony, he and the kids have been seen watching beach volleyball. Brooklyn was able to go along with David to check out a soccer match, too. It's all leading up to Sunday, when mom Victoria Beckham will have a chance to participate. Victoria will perform in the closing ceremony with her old band, the Spice Girls. The finale of the 2012 London Olympic Games will also feature other famous British musicians, like Muse, as well as a catwalk show featuring models like Kate Moss and Naomi Campbell wearing outfits from UK-based designers.
