Carly Rae Jepsen plays it up with patterns on the January 2013 cover of Cosmopolitan mag.

The 27-year-old Canadian sensation chats with the glossy about Justin Bieber, keeping it playful on stage and songwriting. Check it:

On the push Justin Bieber gave her career: “I never get tired of being asked about him. I’m forever indebted to him for the lovely boost that he’s given me.”

On people who say she dresses too young: “I love being classy and as elegant as possible in my apartment. But when I’m onstage, I can’t dance in 4 ½ -inch heels, so I’ll generally sport flats. I’m 5 feet 2, so yeah, I’m going to look a little bit more playful. But I don’t think that means I’m trying for an age younger than I am.”

On seeing her songs come to life: “For me, the goal of music has never been ‘I need to be the biggest superstar in the world.’ It was ‘I want to spend my life doing this, and I want to make a career that I can live off of so I don’t have to tend bar and waitress to make this fly.’ I don’t want to be Cinderella for a night. I want to be Cinderella for life.”
