Justin Bieber performed his hit single "One Less Lonely Girl" on Dick Clark's Rockin's New Year's Eve. Selena Gomez made a surprise appearance on stage. Though she's about four inches taller than him, granted she was wearing heels, it was too cute watching him sing to her!
Justin Bieber is 15 and Selena Gomez is 17. Do you think the two might be dating, or are they just good friends?
