Brave Entertainment's upcoming idol group Big Star jokingly dissed their producer, Brave Brothers at a public event recently.

At SISTAR's showcase, the members of Big Star made the audience explode in laughter when they introduced Brave Brothers with the announcement, "Brave Brothers, who is in charge of SISTAR's productions... Shinsadong Tiger forever!"

Park Sung Kwang and the producer himself were backstage listening to the stage, and cameras caught them both looking surprised after Big Star's statement. Brave Brothers and Shinsadong Tiger are two of the top producers in K-Pop so there's always been talk of rivalry, whether fact or fiction.

Fans can check out the full reaction and the consequences the boys faced on the May 5th episode of 'Brave Brothers Big Star Show'.

Big Star is Brave Entertainment's first male group to debut. The seven members will be going through severe tests before two are eliminated, leaving the final five members to officially debut as Big Star.
