Fat Actress no more! Kirstie Alley showed off her weight loss after squeezing into a tight red dress for a night out in Los Angeles yesterday

She claims not to have weighed herself for the past four weeks, but the effects of appearing on Dancing With The Stars are clear to see.

Kirstie Alley stepped out last night in a corseted red dress which highlighted her newly-slim physique.

And while the former Fat Actress star acknowledges she still has a long way to go, she says she is thrilled with her ever-shrinking frame.

She said recently: 'I haven't weighed myself in the last four weeks. I bought these dresses from a size twelve (UK size 16) to a two (UK size 6). Tonight I'm a six (UK 10). When I'm a two, I'm done, people!'

Kirstie was celebrating in Hollywood last night after narrowly escaping elimination on Dancing With The Stars after the public voted to send Petra Nemcova home.

After making it through to next week's show, Kirstie thanked fans for voting for her and dance partner Maksim Chmerkovskiy and tweeted: 'Yay!!!!!!'we live to dance another week!!!!!! My sex stick and I are happy!!! Woo hooo!!!!'

Kirstie is clearly feeling a lot more confident about her body now, and showed off her slim waist in a jumpsuit with a sheer waist panel as she performed the foxtrot to the track American Woman.

The former Cheers star said before starting her Dancing With The Stars journey that one of the main reasons she was taking part in the show was to shed the pounds.

She told US Weekly magazine: 'I've lost 60 pounds, and I have 30 or 40 more to go.

And I think with this strenuous, rigorous dance schedule, I think it's going to work.'

Kirstie documented her battle with the bulge in reality TV show Kirstie Alley's Big Life last year, and was seen tipping the scales at 16st 4lb (230lb).

But, after she was filmed on the verge of a tantrum on the programme, Kirstie vowed to get down to a slender 9st 7lb through diet and exercise.

Kirstie knows she has the ability to slim down, as she was seen proudly parading her bikini body on The Oprah Winfrey Show in 2006 after losing five stone.
