Ryan Gosling seen onstage with Black Lips at ACL 2012

The news from Austin City Limits just gets better and better! After all the great fan pics and tweets we now know that Ryan and Rooney were seen on stage with the Black Lips!  It seems that Terrence Malick's untitled film puts Ryan in the role of cameraman as he was seen 'filming'

"Austin City Limits always packs a few surprises, but I don’t think anyone was expecting this: A guitar-slinging Rooney Mara joined the Black Lips onstage and rocked alongside them for one song while Ryan Gosling watched from stage left. Oh, and reclusive director Terrence Malick was on hand filming the whole thing." 

 
There is even some video captured of the event!!  Fuse have links to YouTube clips that someone from SlashFilm shot on their cell. Click on the link below to see the clips!!
