Raising Hope's Cloris Leachman: "I'm So Sick of Betty White"

Everyone loves Betty White, but not Cloris Leachman.

"I'm so sick of Betty White," Leachman said at the Television Critics Association's fall previews on Tuesday. "Never liked her."

The 84-year-old actress, who plays a wild, chest-baring granny in Fox's new fall comedy Raising Hope, commandeered the show's session, forcing co-star Garret Dillahunt to switch seats mid-Q&A and reporters to stand up and say their names when asking her questions.

"As can see it's pretty easy. You don't have to do much," Leachman's co-star, Martha Plimpton, said with a chuckle about working with the Oscar and nine-time Emmy winner. "It's a sheer delight." Raising Hope revolves around 23-year-old Jimmy (Lucas Neff), who unexpectedly becomes a dad after a one-night stand with a wanted felon in the first episode. Plimpton plays Jimmy's mom Virginia.

Leachman didn't hold back on the profanity either, asking Plimpton if she had f------ creator and executive producer Greg Garcia (My Name is Earl) in the middle of the panel after Plimpton paid him a compliment. Plimpton admonished her: That's "make-up trailer talk."

Leachman's co-stars should be advised not to get too attached to their out-spoken castmate, who told shared with reporters the exact locations of her Oscar and Emmy awards in her house.

"You bet your life," Leachman said of her hopes to receive a 20th Emmy nomination for the series. "If I don't get an Emmy for this show, I'm leaving."

Raising Hope premieres on Tuesday, Sept. 21 at 9/8c on Fox.
