Joan Jett had better watch her wrinkly old behind, because after this story hits the news waves, the Twilight fans are going to be out for her blood!

An insider on the set of the new Joan Jett biopic The Runaways has revealed that the aging rocker gave Twilight star Kristen Stewart such a hard time last week that the young actress “burst into tears” on set.

“Joan just wants Kristen to play an authentic version of herself,” says the insider, “so she needled her a little bit too much. But she apologized when she realized how upset Kristen got.”

According to the source, the incident has been smoothed over, and any bad blood that was between the two has been washed away. “They’re like mother and daughter now,” the insider added.

Still, Twilight fans are known to be some of the most ruthless in the entertainment world. I doubt they’ll forgive Ms. Jett as quickly as Kristen appears to have done.

Lindsay Lohan and her BFF, DJ Sam Ronson, may not be as “tight” as they once were, with sources claiming the pair had a “full-blown fight” recently that left LiLo in tears.

A source has revealed that the fight took place a few nights ago at West Hollywood’s Crown Bar, where Ronson was deejaying.

“They had a full-blown fight,” the source explained. “Evan Ross, Diana’s son, and Lauren Conrad [from The Hills] comforted her while Lindsay kept wiping her tears.”

Maybe Sam was jealous of Lindsay’s flirtatious relationship with Joel Madden??
