Justin Bieber shares 'Boyfriend' clip, introduces Carly Rae Jepsen on 'Ellen'
The full single will be released Monday. We can hardly wait.
He also introduced Carly Rae Jepsen, the first artist signed to his record label. Carly was previously signed to a small Canadian record label but didn't know how to expand her reach to the states. "And then one miraculous day, Justin called!" she tells Ellen. "No big deal. At the time I was touring Canada in a soccer mom van with my band."
