"TTL (Time to Love)" is the first collaboration single released by South Korean groups T-ara and Supernova. The single was released digitally on September 15, 2009.

Background and release.
"TTL (Time to Love)" is the first project single between T-ara and Supernova. Although both groups are credited on the song, only So-yeon, Eun-jung, Hyomin, and Jiyeon (from T-ara) and Kwangsoo, Jihyeok, and Geonil (from Supernova) participated in the song. Bo-ram and Qri starred in the music video instead. It was Supernova's first release in two years.
The single's success prompted Core Contents Media to produce the sequel entitled "TTL Listen 2", an alternate/remix version of TTL. It was released on October 9 featuring all members from both groups. Originally it was scheduled to be released on the 13th, but due to high fan demands, the groups' agency, CCM, decided to release it 4 days ahead of schedule. Both songs were re-released on T-ara's first album "Absolute First Album" and later on its re-issue "Breaking Heart". The Japanese version of "TTL (Time to Love)" was included in T-ara's first Japanese album. This version is sung only by the members of T-ara. A remixed Japanese version was released on the group's third Japanese album "Gossip Girls" in 2014.
