"If We Ever Meet Again" is the fourth U.S. single and second internationally from Timbaland's third studio album, Shock Value II. The song features Katy Perry as Timbaland's duet partner. Timbaland's brother, Sebastian, is also featured at the end of the song, but is uncredited.
Timbaland told MTV News that will.i.am's work on "I Gotta Feeling" inspired him to make "If We Ever Meet Again": "When I did this song, I was in love with this record called ... you're gonna be surprised. The record didn't have anything to do with ['If We Ever Meet Again'], but when I heard [the Black Eyed Peas'] 'I Gotta Feeling,' I said, 'I want a record just like that on my album.' I said, 'I gotta do me a "I Gotta Feeling" record.' Me and one of my producers, Jim Beanz, we came up with this concept. I said, '["I Gotta Feeling"] is happy, but I like it.' It gives a good feeling".
On the record, Timbaland decided to sing rather than rap. He said this about his desiction: "It's not like it's incredible singing, but it made sense for me and it fits my voice," Timbaland explained. "To get somebody else to sing it, it might sound too overdone. I like it better with mistakes — I make mistakes. With me singing it, it gives it a different kind of swagger to it."

|“||I wanna make something deep, I don't know if I wanna make it like a relationship. I wanna make it like she saved my life with whatever depression I was going through, whether it be drug depression, weight-loss depression — something. ... Will she be around if I go through this again?||”|
The video premiered on January 18, 2010 and from January 19 is showing on UK music channels, charting at number one on many of the music channel video charts.
The video focuses on the love story between a jewel thief (played by Julian Graham) and an art thief (played by Nadine Heimann), interspersed with performance pieces from Perry and Timbaland. In the original video Katy Perry appears in black girdle and black leather as an underwear, while Timbaland in some parts of the clip was in a brown Jacket and with a flat cap on his head. Other scenes had Perry dressed in white, sitting at a table where the story is still taking place around her, while Timbaland is also seen wearing a suit. The video ends with a group of thieves stealing all the artworks and jewels that the jewel thief and the art thief have taken.
