SPOTTED: Jack Black and Tenacious D at a Ghost Ghirls ‘watch party’ event held earlier this week at SXSW.

In celebration of his soon-to-be released web comedy series, Ghost Ghirls, Jack Black attended the SXSW ‘watch party’ viewing, panel and cocktail event hosted by Yahoo! and Shine America. He also performed a great set with Kyle Gass of Tenacious D towards the end of the night. 

Another highlight of the event was the announcement that Dave Grohl will be guest starring in an episode of Ghost Ghirls alongside Jack Black and Val Kilmer.
