Anything can happen when you're hanging out with British pop star Ellie Goulding! The singer posted a party pic that included a slightly hidden Kristen Stewart. Donning a pair of thick-rimmed glasses and a backwards baseball cap, the Twilight leading lady's face is peeking out behind a guy posing in front of her. Goulding captioned the Instagram pic, writing: "Nice face bro. Post Wiltern. EPIC show thank you! Xxx"
