PHOTOS: Kristen Stewart & Dakota Fanning On Stage With Joan Jett

Kristen Stewart and Dakota Fanning joined Joan Jett on stage Saturday night in Park City, Utah at the Harry O’s Concert Series.  All three ladies are at Sundance to promote ‘The Runaways’, a biopic about Jett’s 70’s band.

Jett called Kristen and Dakota up on stage to the delight of the packed house. The girls waved and smiled before heading backstage to watch the rest of Joan’s show.

The Runaways premieres Sunday at the Sundance Film Festival.
