George Lopez is getting some heat for insulting this season's "Dancing With The Stars" contestants on Wednesday's episode of "Lopez Tonight."

In his stand-up routine, the talk show host compared Kirstie Alley to a pig and accused Ralph Macchio of wearing a hairpiece.

"She did a nice job, her little hooves tapping away," Lopez said. "Before the show, she went to the market, and then she had roast beef and this is her going all the way home..." Then the show cut to the Geico "Little Piggy" ad of a pig screaming "weee."

Alley has struggled with her weight for years but said earlier in the month that the weight is already "melting off" preparing for the dancing competition. The actress has also dropped about 60 pounds in recent months and credits her new diet program, "Organic Liaison." Alley's representative had no immediate comment.

Of Macchio, who had the high score of 24 out of 30 in the twelth season premiere, Lopez said, "He cut a mean rug, then took the rug that he cut and glued it to his head."

Lopez said that for reality star Kendra Wilkinson to calm her nerves, she "pictured the audience picturing her naked," which was followed by a joke about the Playboy model checking Hugh Hefner's prostate.

Lopez didn't spare talk show host Wendy Williams, he suggested that Williams is a man several times before saying, "the last time she cried that hard is when she was on 'Maury' and he said, 'Wendy Williams, you are the father.'"

Lopez's wife Ann filed for divorce in November 2010 after 17 years of marriage, following rumors that the comedian had cheated. In 2005, his wife donated a kidney to Lopez, who suffers from a genetic ailment.

Update on Friday, March 25: George Lopez apologized and Kirstie Alley said she forgives him.
