Carly Rae Jepsen, ever-bubbly creator of the catchy "Call Me Maybe" hit single has high hopes for her musical mentor Justin Bieber. After the Biebs tweeted about her and made a lip sync sing-a-long video to her track that went viral, Jepsen became a star -- so clearly, she has good feelings toward the 18-year-old. After his recent Grammy snub, the Believe hitmaker's manager Scooter Braun made his disapproval apparent, but Justin seems to be handling the disappointment fairly well. If the 27-year-old Canadian is right then 2013 will only have more success in store for Bieber.
