Lindsay Lohan thinks Gwyneth Paltrow is a mean girl.
During Paltrow's guest-starring role on Glee last month, her character (a quirky substitute teacher) made cracks at Lohan's expense, quipping, "Lindsay Lohan is totally crazy, right? How many times has Lindsay Lohan been to rehab?"
Turns out Lohan, 24, caught the episode at the Betty Ford Center. "Lindsay is so upset with Gwyneth," her mom Dina tells Radaronline. "She called me and was upset and said, 'Why did [Gwyneth] have to do that?'"
The mother added: "Gwyneth went overboard and it was unnecessary. Lindsay thought she was a friend and it was disappointing...It was hurtful and not funny."
As per a judge's orders, Lohan -- who violated probation in her DUI case due to a failed drug test -- will remain at the Betty Ford Center in Rancho Mirage, Calif. until Jan. 3.
