Baby

This is the lead single from the latter half of Canadian pop singer Justin Bieber's debut album, My World (Part II). Ludacris also features on the track rapping about his first love.

Justin co-wrote the song alongside Christopher "Tricky" Stewart and Terius "The-Dream" Nash. The duo also worked with the Canadian teen on his debut single "One Time." Ludacris and R&B singer Christina Milian also contributed to this track.

Justin told Digital Spy that this is a song everyone can relate to. He explained: "I'm basically saying I really like this girl and would do anything to make her my girlfriend."
