Debuting in June 2010 with the popular single "Push Push," the girls' contract will be expiring soon as they signed a standard 7-year contract. Ahead of their contract expiring, SISTAR is expected to make a comeback on May 31 with a song by Black Eyed Pilseung who previously produced their tracks "Touch My Body" and "I Like That." As SISTAR's comeback coincides near the timeframe when their contract expires, there is additional interest in the contract renewal situation.
A representative of Starship Entertainment commented, "The girls are currently in discussion of renewing their contract."
Meanwhile, many are wondering if SISTAR will continue to work under Starship Entertainment as they have had a good seven years under the label. SISTAR also have begun filming for their new music video in Macau.
