The original Justin Bieber was Jesse McCartney.  Am I wrong?  Ok, I am.  There aren't a lot of similarities between the two aside from the fact they're both cute and young.

"Body Language" from 2009 was the second single from his "Departure" album.  You'll probably hear the line, "The thing you got behind you is amazing" which was exactly the same line from the only two released singles off that album.  The other one being "Leavin."

When Jesse was just 20 years old in 2007, he co-wrote the hit song "Bleeding Love" with Ryan Tedder of OneRepublic. It was produced by McCartney and Tedder for McCartney's third album. But--he gave it away to English singer Leona Lewis for her debut album, "Spirit."
