This week in the world of social media, it was all about good friends and good times as celebrities shared their action-packed photos for us to enjoy. Jessica Alba took her Summer fun one step further (and gave us a pretty awesome weekend idea) by floating in a kiddie pool. Claire Danes showed off her pregnancy glow for photographer friend Amanda de Cadenet, while the Spice Girls posed with Russell Brand backstage during the London Olympics closing ceremony. The ladies of The Vampire Diaries also got in on some girl time. They beat the Summer heat by slipping into their bikinis and taking a dip in the pool together.
