Alley has lost 38 inches since `Dancing' debut

When Kirstie Alley performs on the "Dancing With the Stars" season finale, she'll do it in a much smaller dress than the one she wore on the season premiere.

Alley says the costume she wore for her "Dancing" debut had to be taken in 38 inches for her to wear it again for performance on Tuesday's closing episode.

Alley will reprise her opening-night dance, the cha-cha, in her original costume.

The 60-year-old actress has been noticeably shrinking week after week, but she was coy Monday when asked how much weight she has lost during her two and a half months on the show, saying, "I really didn't care."

A new "Dancing" champ will be named Tuesday. Alley is up against actress Chelsea Kane and football star Hines Ward.
