"Lovebug" is a song by the American teen pop band, the Jonas Brothers. It was released as the second official single off their third studio album, A Little Bit Longer, on September 30, 2008. Lyrically, "Lovebug" is about being smitten by girl for the first time and attracting feelings for said girl from that moment. A music video was released to accompany the single and is a period piece romance that was inspired by The Notebook.

The song was written while on tour with Miley Cyrus on her Best of Both Worlds Tour. Nick said that "we were in the hotel room and sat down that night and wrote it in about 15 or 20 minutes." The song first premiered at the 2008 MTV Video Music Awards when the Jonas Brothers performed it at the back lot of Paramount Studios in Hollywood, California.

Disney Channel featured the world premiere of the "Lovebug" music video on October 19, 2008 (8:55 p.m., ET/PT). An exclusive look at the making of the video was presented throughout the evening (8:00- 9:00 p.m., ET/PT) during episodes of Hannah Montana and Wizards of Waverly Place.

Directed by Philip Andelman (who has directed music videos for John Mayer and Demi Lovato), is a period piece that depicts the love story between a young woman and a sailor as he is preparing to deploy to war. Kevin Jonas said that The Notebook was one of the inspirations for the video.

Kevin, Joe and Nick portray multiple characters, including members of a ballroom band. A sweeping dance number, vintage wardrobe and cars bring the Jonas Brothers’ vision to life. Camilla Belle and Josh Boswell also star.
