Kristen Stewart and Joan Jett have been photographed leaving a studio together.
They were practising for a new film about seventies girlband The Runways, of which Joan Jett was a member.
Jett, real name Joan Larkin, looked youthful despite turning 50 recently. 19-year-old Twilight star Kirsten Stewart has cut her hair and died it back in preparation to impersonate the legend
Kirsten can already play guitar, but has been taking singing lessons with Joan.
Kristen said: “I'm just listening to her music all the time. I'm trying to just make myself aware of the time period and what she was going through.
“It's one of the most immense responsibilities to play a real person. Her story's important. It's an incredibly triumphant feminist story really.
“She's the first woman to ever start her own record label. So many people know her as just being like one of the coolest people to ever live. That in itself is one of the most intimidating things that I've ever had to confront but she's so cool too.”
The film also features New Moon co-actress Dakota Fanning as Runaways frontwoman Cherie Currie.
