On Wednesday's Lopez Tonight, Lopez cracked on that Alley did a nice job on Dancing with the Stars with "her little hooves tapping away." "Before the show she went to the market, and then she had roast beef, and this is her going all the way home," Lopez said, showing a clip of a pig with its head hanging out the window of a car.

Alley, who earned a 23 for her cha-cha on Monday, didn't seem too worked up about Lopez's remarks."Don't worry about George's comments," Alley tweeted earlier Thursday. "Just remember what happens to the big bad, drunk woolf [sic] ...falls in a boiling pot of vodka. Piggy laughs."
