Emily Ratajkowski took some time to hang out with "Extra's" AJ Calloway at our H&M studio in NYC. The 24-year-old beauty has capitalized on her big break in Robin Thicke's music video "Blurred Lines." She is now starring in "We Are Your Friends" opposite Zac Efron. On her girlfriends' thoughts about her working with the heartthrob, she said, "They were "very very happy. I mean he's Zac Efron, c'mon."
