In 1985, Anderson graduated from Highland Secondary School. In her high school yearbook, she wrote that she wanted to be a California beach bum. In 1988, Anderson moved to the city of Vancouver, where she got the taste of a city life and worked as a fitness instructor. During the summer of 1989, Anderson and her friends went to a Canadian football game. At some point during the game, Anderson was shown on the stadium screen. The crowd at the game cheered for the young Anderson, then 21. Anderson was taken to the field to get an ovation from the crowd.
After her move to Los Angeles, Anderson dyed her hair blonde and got breast implants to enhance her look. In 1991, Anderson landed a minor role on the United States hit television sitcom Home Improvement (1991-1993). Gaining the attention of viewers, she got the role of C.J. Parker (1992-1997) on Baywatch.
Later, she quit Home Improvement. Anderson was still modeling for Playboy and appearing on the cover of the magazine each year. Her role as C.J. Parker gave Anderson more popularity and attention from international viewers.
In March 2001, Christine Evelyn Roth was arrested while sleeping in a guest room of Anderson's home. She was only charged with the misdemeanor of trespassing and not the more serious crime of stalking. Roth pled guilty to the charge of trespassing and was deported to her home country, France.
It was announced on July 18, 2006 that she will marry Kid Rock on July 29, 2006 on a yacht near St. Tropez, France. "Feels like I've been stuck in a time warp," said Anderson in her internet diary entry. "Not able to let go of MY family picture ... it's been sad and lonely and frustrating ... I've raised my kids alone in hope of a miracle. Well my miracle came and went. And came back and back because he knew that I'd wake up one day and realize that I was waiting for nothing." "I'm moving on," she declared. "I feel like I'm finally free ... I'm in love." There has been extensive unconfirmed media speculation that the marriage is pregnancy-related, but the theory is based only on Anderson's representatives refusal to comment on the question.
