Cameron Diaz kicked off the weekend on Thursday, March 27, 2014 with a red carpet appearance, wearing an oh-so-chic gray Victoria Beckham frock and white pumps to CinemaCon in Las Vegas.

The celebrity festivities continued with the Divergent European premiere in London (um, is it just us or did that blue Stella McCartney gown on Shailene Woodley make her seem 7 feet tall?), and of course, the Nickelodeon Kids' Choice Awards stateside. The usual suspects like Lea Michele (looking gorgeous in Elie Saab), Selena Gomez, and Victoria Justice all made appearances, but our eyes were trained on Zoey Deutch. The 19-year-old Vampire Academy looked kind of like an older, brunette Kiernan Shipka in an Osman top-and-shorts set.
