The last time Kirstie Alley was on the show, in season 12, she basically transformed herself, losing a lot of weight and becoming notably light on her feet by the end of the season. The 61-year-old star of Cheers, Veronica’s Closet, Look Who’s Talking, and Fat Actress claimed that her “biggest challenge is to move quickly enough—if someone told me to haul ass, it would take two trips.” But she was impressively lithe, making it all the way to the finale before losing to fan favorite Hines Ward. As an all-star, she’s reunited with her partner Maksim Chmerkovskiy, with whom she has a delightfully flirtatious and bantering rapport.
