Leavin' (Jesse McCartney song)

"Leavin'" is a song by American singer-songwriter Jesse McCartney, released as the lead single from McCartney's third studio album Departure (2008). Written and produced by Tricky Stewart and The-Dream, with additional writing by James Bunton and Corron Ty Cole, "Leavin'" was sent to U.S. mainstream radios on March 10, 2008.

Namesake of the album's title, "Leavin'" was considered a departure from McCartney's youthful image in favor of adult-oriented subject matter, vocal delivery and production. Lyrically, the song finds McCartney admiring a female's backside with plans to steal her from her current beau. Sonically, the song is pop with an electro production style and sound effects from digital watches, alarm clocks and kitchen timers. Its music video shows the singer admiring a model before kissing her at the end.

"Leavin'" remains McCartney's biggest hit single in the United States, reaching number one on the Billboard Mainstream Top 40 chart and peaking within the top 10 of the Billboard Hot 100; it sold over three million digital downloads and received triple platinum certification by Recording Industry Association of America (RIAA). Worldwide, it entered the top 20 in Canada and became a top-40 hit in France, Ireland, and Scotland.
