"Lovey-Dovey" is a song by South Korean girl group T-ara from their fourth extended play Black Eyes (2011) repackage, Funky Town (2012). It was released as the lead single on January 3, 2012. A thirty-second teaser of "Lovey-Dovey" was unveiled at the end of their "Cry Cry" music video, with a full one-minute teaser released on November 30, 2011.
Written and produced by Shinsadong Tiger and Choi Kyu-sung, "Lovey-Dovey" is an electropop song with strong beats, and the instrumental features the use of cowbells and scratching. The song is described as being influenced by the "trendy club music popular in Europe and the United States". The lyrics are about the protagonist feeling lonely without, as well as seeking for, their love interest.
"Lovey-Dovey" reached number one in South Korea as well as number one on the Billboard Korea K-Pop Hot 100 chart. Five music videos have been produced for the song, but only three of the five have been released to date. The first version is a continuation of their earlier "Cry Cry" drama music video, the second features a zombie concept, and the third follows the group traveling and promoting around Tokyo, Japan. The song won a total of thirteen number one awards on various South Korean music shows: four on Music Bank, four on Music on Top, three on Inkigayo, and two on M! Countdown.
