Joan Jett loves rock and roll and, by the looks of it, rock and roll loves her too.



Here's the 22-year-old former Runaways member back in 1981 (left) -- and 29 years later, the 51-year-old at her NYC film premiere this week (right).

She's a rock goddess.

Former Runaways members Joan Jett, 51, and Cherie Currie, 50, reunited in NYC on Wednesday.



Question is ...

Joan Jett just fired off a lawsuit against former Runaways band member Jackie Fox saying she's ticked Fox is trying to cash in on the band's name, a trademark Jett says she owns herself.



In the suit -- which reads like a "Behind the Music" of the rockin' 70s girl group -- Jett alleges her former bassist has "threatened" her business partners, claiming she also has the right to be paid for the use of the Runaways trademarks.

Jett says Fox has also been a nuisance with the production of the band's biopic, starring Kristen Stewart, saying Jackie has tried to halt filming until she sees/approves a script. According to Joan, there is no character based on Jackie in the movie.

Joan is seeking damages suffered from Fox's alleged meddling and a declaration from the court saying Fox has no right to the band name or any money made from it.

Attention all you crazy Edward Cullen fans -- this video won't get you any closer to the bloodsucking bad boy, but you can at least take joy in knowing the girl he does sink his teeth into totally ate pavement on a movie set.


Though Kristen Stewart was filming as Joan Jett in "The Runaways," she totally pulled a Bella Swan -- by clumsily hurling herself into the sidewalk.

Trust us, this wasn't in the script.

Emo princess Kristen Stewart showed off her brand new punk rock shag cut in L.A. today.



The 19-year-old has gone black to play Jared Leto Joan Jett in the new biopic about the '70s female rock band The Runaways.

Looks like Kristen and Robert Pattinson are in for a hair war!

In the '80s, Joan Jett proved how much she loved rock-n-roll. Guess what she looks like now!

Carmen Electra and her gal pal, '80s rocker Joan Jett, enjoyed a girls lunch in the West Village on Monday.

While the dynamic duo stepped out in similar shades and hoodies, Carmen strutted around town in black wedge sandals as Joan kept her rocker cred in a pair of motorcycle boots. Girls will be girls!

Joan and Carmen have been best buds ever since Electra starred in Jett's "ACDC" music video. Rock on ladies!
