Kirstie Alley is not one to mess with! Kirstie accepted George Lopez's apology for making jokes last week that implied she was a pig, but the "Dancing with the Stars" contestant had some choice words for Lopez following her performance on Monday night's show.

"He's a bitch but whatever," Kirstie said. "You know, he's a comedian. Comedians say what they want to say. It's not like he's the first comedian that's said anything."

David Letterman offered an apology to Kirstie last year for making wise cracks related to the actress' weight gain after she became a spokesperson for Jenny Craig.

"It took me a while to come up with some good comebacks," said Kirstie, who tweeted, "[George Lopez] I don't need or want your apology... I want your kidney dude..on behalf of your ex and all the women you've insulted... give it back," before publicly accepting the comedian's apology.

In 2005, George Lopez underwent a kidney transplant with his estranged wife, Ann, as the donor. The couple filed for divorce in 2010.

Kirstie's pro dancing partner, Maksim Chmerkovskiy, said that when he first learned of the feud "[he] was sorry for George."
