Brian Austin Green, Harold Perrineau

TBS announced Friday that Brian Austin Green and Harold Perrineau have joined the hourlong comedy pilot, The Wedding Band.

The project follows a group of guys who perform in a wedding to escape the stress and chaos of their daily lives. The band is led by best friends — one bachelor and one a married father of two — who make sure every event is memorable. Wedding Band also stars Peter Cambor (NCIS: Los Angeles) and Derek Miller (Secret Girlfriend).
