Kirstie Alley was born on January 12, 1951 in Wichita, Kansas. Alley attended Kansas State University and the University of Kansas for a short time, dropping out during her sophomore year to pursue an acting career. Her first TV appearances were on game shows - in 1979 she appeared on Match Game and won $6,000, and in 1980 she appeared on Password Plus.Alley's first major role was as supporting role in the hit 1982 movie, Star Trek II: The Wrath of Kahn, where she played Lieutenant Saavik. Star Trek II was a major hit and Alley was offered a role in Star Trek III, which she turned down when the producers failed to meet her salary demands.
Alley later had a major role in the popular TV miniseries about the Civil War, North and South. Alley also had minor roles in other movies and TV shows throughout the mid-1980s until she was cast in her career-defining role as Rebecca Howe, the manager of the Cheers bar on the sitcom, Cheers. 
Fans of Cheers liked Alley's character on Cheers - she was a very attractive woman and definitely had acting abilities and comedic talent. Alley won an Emmy for her role in 1991. Alley co-starred on Cheers from 1987 until the series finale in 1993. 
While Alley was on Cheers, she also found time to appear in several popular major motion pictures, including Shoot to Kill, Look Who's Talking, and Look Who's Talking Too. After Cheers went off the air in 1993 Alley continued acting in minor roles on various TV shows and movies through the mid-late 1990s. In 1997 she was cast in the starring role of Veronica's Closet, a sitcom about the head of a lingerie company. Veronica's Closet ran for three seasons, until its cancellation in 2000.
After the cancellation of Veronica's Closet, Alley cut back on acting a little bit and turned to the other passion in her life - greasy and fatty foods. Although once known as one of the sexiest actresses on TV, Alley tarnished her image by adding at least 100 lbs of pure fat to her body, becoming a morbidly obese woman and reportedly topping the scales at over 300 lbs. Her fans were shocked and saddened to see her so overweight. 
Alley, however, maintained a good nature and decided to do something about her appearance - she starred in the 2005 mockumentary, Fat Actress, a sitcom inspired by real events in Alley's life. Alley also became the spokeswoman for Jenny Craig and kept to a strict diet between 2004 - early 2008 when she was fired for being too fat. During her reign as spokeswoman, Alley kept to a strict diet, eventually trimming down to 145 lbs at one point. 
However, after being fired as spokeswoman, Alley stopped exercising and pigged out on food once again and has admitted that she has gained 83 lbs since early 2008. 
Kirstie Alley is apparently addicted to Hostess Ho-Ho's and Ding Dongs, and almost certainly purchases 2-lb bags of M&M's and cuts open the bags and pours all of the M&M's directly into her open mouth. Although Kirstie Alley has had a very successful acting careers, the fact that she morphed from one of the hottest actresses in Hollywood into a morbidly obese hog means that Kirstie Alley is one washed-up celebrity!
