The "Call Me Maybe" singer says she learned to make time for fun from the Biebs. "Justin leads by example. I love that he works hard and has fun," she said.

"I was in Paris promoting my new album, Kiss, for three days with no time off. So I went out at four in the morning to go explore the entire city. I try to make moments happen that feel very special and memorable because that's exactly how Justin does it."

Carly has had a whirlwind year but manages to make time for her new boyfriend singer Matthew Koma.
