Newly-engaged actress Emma Roberts fears she has become obsessed with One Direction pin-up Harry Styles, because she can't stop talking about him or singing his tunes. The We're The Millers star, who recently became engaged to actor Evan Peters, admits she can't get enough gossip about Styles and his bandmates and belts out their hits in her car when she's driving around Hollywood. She explains, "I'm blasting it (song) in my car with the windows down (and) I'm lip syncing the whole thing and I'm always scared I'm gonna pull up to, like, my friend's mum and she's gonna be like, 'Hey, what are you doing?'" She adds, "My little sister and I talk about One Direction all day. I'm scared if someone ever saw my phone; I'm like, 'Delete these messages...' It's like, 'Harry Styles, Harry Styles, Harry Styles...' To all of my friends, it's like, 'What do you think Harry Styles is doing, do you think he's in L.A.?'" But Roberts has gotten closer to her pop idol and his bandmates than most fans - she bumped into One Direction at an awards show. She adds, "I have, like, 100 selfies on my phone with all of them. Afterwards I was so embarrassed."
