Angelina Jolie shopped in LA this afternoon with her youngest children, Knox and Vivienne Jolie-Pitt. Also along for the retail outing to Auntie Barbara's Kids Boutique was Brad's mother, Jane Pitt. Angelina spent the day with family after hitting the red carpet at yesterday's Oscars. In Atelier Versace, Angelina Jolie turned more than a few heads thanks to a serious slit in the black velvet gown. She presented honors to the year's best screenwriters, and one group of honorees, from The Descendants, playfully mocked Angelina's onstage pose. The gesture didn't seem to bother Angelina much, as she and Brad segued right into their afterparty fun. Brad and Angelina met up with George Clooney, Emily Blunt, John Krasinski, and Salma Hayek at a private bash Clooney hosted at Craig's restaurant.
