Chelsea Handler isn't impressed by Kirstie Alley's much-talked-about weight loss on Dancing With The Stars.

She stopped by The Joy Behar Show and said she hates DWTS, but admitted to watching Alley ... for some not-so-nice reasons.

"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 can't watch that show."

She called DWTS a "ridiculous program." Her explanation of why she didn't accept ABC's offer to do the show? "Because I have a job."

See the latest pics of Alley at DWTS rehearsal after the jump and in our gallery below.

Handler admitted that Alley "hates" her. Handler is known for making enemies of other celebs; she came under fire in the past for calling Angelina Jolie the "c" word, but told Behar she would never apologize for it.

The comedienne is also known for openly discussing her dating life. She was rumored to have been dating rapper 50 Cent. See what she said about the relationship after the jump.

Kirstie Alley almost passed out at Dancing With The Stars rehearsal, then revealed it was because she had only eaten 150 calories so far that day. Alley has gotten praise for her weight loss, but we were worried she wasn't being healthy!

Luckily, the actress made time to grab a bite. She also made it through to the next round on the show earlier this week, and scored her first 10 from a judge!

Kirstie Alley has been praised for her weight loss on this season's Dancing With The Stars, but are her eating habits getting dangerous? The actress fell twice in rehearsal this week (see video), telling partner Maksim Chmerkovskiy that she felt like she was going to pass out.

Then, Alley revealed that she'd only eaten about 150 calories so far that day, and was only eating 1,400 calories a day total on average.

But do less calories translate into higher scores? The duo performed well, receiving a two 9's and a 10 from the judges. Judge Bruno Tonioli told Alley, "Your body is shrinking, but your talent is huge!"

After their performance, Chmerkovskiy again expressed his distress. "She's not eating," he said. "She's not eating." Alley's explanation? "I forgot," she said.

Speculation is that Alley has gotten down to a size 6; she addresses her size after DWTS rehearsal in our video.

The actress was making plenty of waves on last night's episode; she also accidentally yelled "s***" during the judges' critiques! Check out the video after the jump, and see our gallery for pics of Alley leaving Katsuya in Hollywood Monday night - hopefully she had something to eat!

Kelly Preston joined gal pal Kirstie Alley for George Clooney's 50th birthday celebration at Mr. Chow. Also there to wish gorgeous George some birthday wishes ... Preston's daughter, Ella Bleu.

Ella, whose dad is John Travolta, has nabbed a role in the upcoming film Gotti: Three Generations. We have a feeling she didn't have to audition since dad is playing the part of Gotti. Lucky, lucky.

Check out Kirstie Alley's 60-year-old svelte figure. Dancing With the Stars has done her body good!

Kirstie Alley has gotten attention for her Dancing With The Stars weight loss lately, but she's certainly not getting a big head.

Reports have been that the actress is down to a size six. "A stretchy six," Alley joked as she left rehearsal.

Alley also quipped that she was so sweaty she looked "like a drowned rat." The 60-year-old has been holding her own DWTS, and has been getting in some extra "practice" at Hollywood nightclubs with an unidentified man.

Alley thanked her fans profusely as she left rehearsal, and apparently she can back it up on the dance floor and in her car!

Dancing With The Stars fan favorites Kirstie Alley and partner Maksim Chemerkovskiy, stopped by The Ellen DeGeneres Show where they were gifted with much safer Dancing costumes, courtesy of Ellen!

The talk show host gave the stars a bubble wrap dress, vest and pants, so all of their parts will be protected if they fall!

Maksim was so excited, he decided to test out his new bubble wrap vest, but quickly took it off once he started dancing -- thank you Maksim!

Kirstie also left the host with a signed pair of her dancing shoes to auction off for the Gentle Barn, Ellen's pet charity.

Dancing With the Stars pro dancer Maksim Chmerkovskiy needs to be given an award for getting partner Kirstie Alley's body looking this fit! Samba obviously does a body good.

The former Cheers star showed off her toned curves in a form-fitting red dress while heading to Cecconi's in West Hollywood for dinner.

Alley said recently:

“I started out in a size 12, then an 8, and then I think next week I’ll be in a 6. The real size I want to be in is probably a 4 or a 6. That’s where I look best.”

See Kirstie's tight tush ... after the jump.

60-year-old Kirstie Alley has had her share of mishaps on the DTWS dance floor -- a fall followed by a shoe malfunction -- so last night she brought in a "dance doctor" to help with her foxtrot: BFF John Travolta!

Travolta visited Kirstie and partner Maksim Chmerkovskiy to give them advice, like wearing gym shoes instead of Mahnolos and fixing the "sexual tension" between them. Unfortch, Tony Manero's appearance didn't elevate her performance that much.

Alley scored a 23 out of 30, one point better than she did last week, to put her at the middle of the pack.

After the show, Kirstie headed out to The Colony where she took over the DJ decks in her debut as "DJ Lil Buttercup"!
