SUPERBAD star Michael Cera is continuing to dabble with plans to launch a music career after joining rockers MISTER HEAVENLY onstage in Seattle, Washington on Tuesday (30Nov10).
The actor showed off his skills on the bass guitar during the gig, when Mister Heavenly performed in support of Passion Pit.
But Cera is not giving up acting for good just yet.
A representative for the band's Sub Pop record label tells, "As of right now he is not an official member, just playing with the guys on this tour."
It wasn't Cera's first time onstage at a concert - he joined rapper Too $hort for an unlikely collaboration at a show in Los Angeles last month (Nov10), alongside his actor pal Clark Duke.
