Joan Jett has a black heart for a former bandmate.
The hard-rocking frontwoman is suing a bassist of her first band, the Runaways, for blocking a film about the all-girl hard-rock group.
Jacqueline Fuchs, a k a Jackie Fox, who played for the band from December 1975 to June 1977, claims to own a piece of its trademark and has gone out of her way to disrupt the biopic, titled "The Runaways."
"Fuchs tried to have the film halted and has demanded to see the script, even though there is no character based on her," says a lawsuit filed by Jett in Manhattan Supreme Court.
"It's been an ongoing fight," said Jett's lawyer, Oren Warshavsky. "With the movie coming out soon, we need to resolve this once and for all."
