On his show Tuesday, Lopez critiqued Alley's Dancing With the Stars debut, saying she "did a nice job, her little hooves tapping away.
Alley shot back on Twitter, telling fans: "Don't worry about George's comments...just remember what happens to the big bad, drunk woolf...falls in a boiling pot of vodka. Piggy laughs."
Her Tweet prompted Lopez to apologize late Thursday. "I misjudged the joke," he Tweeted. "No malice was intended and I apologize to Kirstie.
Alley Tweeted back to Lopez (whose ex wife donated a kidney to him in 2005): "I don't need or want ur apology...I want your kidney dude..on behalf of ur X and all the women uv insulted...give it back."
Lopez reiterated how sorry he is on The Billy Bush Show Friday, according to Access Hollywood: ”[It was] poor judgment. As they say in my world of golf, ‘bad form on my part.' I’ve apologized. I think she’s accepted my apology, I wish that she had and that she would be guest on Lopez Tonight. I would love to have her on.
