Cameron Diaz and Alex Rodriguez left a pub and walked back to their hotel in London late last night before packing their bags and heading to Paris this morning. The duo made the trip overseas after spending time together in Miami, where they dined out with former President Bill Clinton and partied at a friend's charity event. Cameron and Alex have been inseparable lately, traveling to Mexico and Hawaii between work obligations. Cameron also made time to hang with pal Naomi Campbell during her stay in the UK. The friends apparently picked up where they left off following their tropical New Year's vacation and had dinner and drinks at Nobu on Saturday, perhaps celebrating the continued success of The Green Hornet.
