This is a song by American R&B recording artist Chris Brown, from his fourth studio album, F.A.M.E.. Brown wrote the song, which features Canadian pop singer Justin Bieber. It finds the duo singing about their love for a lucky girl. Breezy returned the favor to Justin when he added a part to the remix of "Up" on the Biebster's, Never Say Never - The Remixes album.

Canadian songwriting and producing duo The Messengers, who comprise singer/lyricist Nasri and multi-instrumentalist/arranger Adam Messinger, produced the song. Their previous collaborations with Brown include the ballad "Crawl". The Messengers have also co-written a number of Bieber's tunes, including his hit singles "Pray" and "Never Say Never."

Chris Brown was just 16-years-old when his debut single, "Run It!," topped the Hot 100, so can identify with the young Canadian. "Being able to collab with [Bieber] was great," Brown told MTV News. "He's a young, energetic cat, so being able to work with him, with the fanbase he has, was incredible. I know a lot of little girls are going to love this record.

I wouldn't say [he's] my protégé. He's doing his thing at a young age, and I was doing mine at a young age, so being able to see him come up is dope."

Brown admitted to MTV News that Bieber and him didn't quite meet up in the studio. "I actually stood him up on accident," recalled Breezy. "He was kind of mad... I was all the way on the other side of town handling some business, 'girl business,' and I was rushing back, and by that time, he's like, 'Man, I'm leaving, bro. I did it — just check it out.' And I looked at it and listened to it and I was like, 'Man, this is crazy.' He's a great kid."
