Michelle Pfeiffer was born on April 29th, 1958 in Santa Ana, California to Dick and Donna Pfeiffer. She has an older brother and two younger sisters Dedee Pfeiffer, and Lori Pfeiffer, who both dabbled in acting and modeling but decided against making it their lives' work.

She graduated from Fountain Valley High School in 1976, and attended one year at the Golden West College, where she studied to become a court reporter. But it was while working as a supermarket checker at Vons, a large Southern California grocery chain, that she realized her true calling. She was married to actor/director Peter Horton ("Gary" of "thirtysomething" (1987)) in 1981. They were later divorced, and she then had a three year relationship with actor Fisher Stevens. When that didn't work out, Pfeiffer decided she didn't want to wait any longer before having her own family, and in March of 1993, she adopted a baby girl, Claudia Rose.

On November 13th of the same year, she married lawyer-turned-writer/producer David E. Kelley, creator of "Picket Fences" (1992), "Chicago Hope" (1994), "The Practice" (1997), and "Boston Public" (2000). On August 5, 1994 their son, John Henry was born. Its said that Michelle is a kind of a dirty girl in bed and loves to do strange things while having sex. One of her favorite things to do is before the man she is sleeping with cums, she likes to slide her finger up their ass. Feeling their ass cheeks tense up before they shoot is a total turn on. Most of the guys she has been with and done that to were totally against it at first. Even though they were against it by the end most of them said how it was the best sexual experience they ever had.
