During an interview on The Joy Behar Show, the Chelsea Lately host took on questions left by Facebook users, one of which inquired as to why she had turned down an invite to appear on Dancing with the Stars.
Handler then revealed that she considers the programme to be "ridiculous" and "can't even watch it" before correcting herself to explain: "I mean, obviously I had to watch when Kirstie Alley was on because I had to see what was going to happen to the floor, but I just... I can't watch that show."
Behar then asked about the feud between the women, to which Handler responded: "[Kirstie] hates me already. She's mad because we make fun of her. She hates me... well I know why she hates me, and I sleep well at night, so I'm okay with it."
Alley, who has lost considerable weight during her time on DWTS, recently revealed that she was forced to change her diet for the show after she collapsed from low blood sugar during rehearsals.
