Gwyneth Paltrow called her grandmother Mutti, but looking back, she has another nickname for her mother's mother.
Appearing on "Chelsea Lately" Monday night, Paltrow spoke about the tough time she had relating to her mutti. Both Handler and Paltrow reminisced about their German grandmoms, and when Handler called hers a "b**ch," Paltrow one-upped her.
"My grandmother was a real c**t," Paltrow laughed. "She basically hated my guts. She tried to poison my mother against me, but it didn't work because I have a great mother. She was just tough, just tough. You look back and you think she must not have been very happy and she must have had a lot of pain because she was mean as hell."
Of course, Paltrow appeared on the show to do a lot more than just insult her grandmother. She was promoting her new cookbook, "My Father's Daughter," and told a story about why she began eating healthy -- and how her daughter helped snap her out of it.WATCH:
