Ulzzang at the time, were added to T-ara. In early July 2009, the group was moved from Mnet Media to its
subsidiary company

Radio Star talk show on July 29, 2009, which was unusual for Korean artists who usually debuted on music programs instead. They made their debut performance on
Mnet's
M Countdown on July 30, performing their debut single "
Lies", along with its
B-side, "Wanna Play?". On July 30, CCM announced that just one day after debut, the group had already received 13 invitations to appear on
