Tori Spelling (Donna Martin)
Daughter of TV mogul and Beverley Hills producer Aaron Spelling, Tori Spelling starred as Donna Martin in the show for the full run.
After the show ended, Spelling starred in several independent films including 'Trick' and 'The House of Yes'.
Spelling has also been the star of two reality shows. The first, which aired in 2006, was the VH1 sitcom 'So NoTORIous', in which she parodied herself. In 2007, she and her second husband Dean McDermott starred in the show 'Tori & Dean: Inn Love' about their purchase and operation of a California B&B. The show morphed into 'Tori & Dean: Home Sweet Hollywood', where the couple return to Los Angeles and struggle to balance buying a new home, her second pregnancy and her book tour.
She also appeared in two episodes of '90210' in 2009.
Aside from her acting career, Spelling has written two books ? 'sTori Telling' and 'Mommywood', with a third in the pipeline, tentatively titled 'uncharted terriTori'.
After her father's death in June 2006, Spelling was expected to inherit a sizeable chunk of the $500-million estate, which was to be divided primarily between Spelling, her brother and her mother, who was the estate's executor. Spelling and her brother received a measly $800,000 each.
She married actor and playwright Charlie Shanian in 2004, but the couple separated in December 2005 after Spelling fell in love with current husband Dean McDermott. The pair were divorced in April 2006 and Spelling and McDermott married less than a month later.
Spelling has two children ? a son who was born via emergency caesarean section in 2007, and a daughter.
In July 2007, Spelling became a minister to marry a gay couple.
Shannon Doherty (Brenda Walsh)
Following reports of on-set friction with her co-stars and bad publicity generated by her off-screen behaviour, Doherty was fired from the show after the fourth season in 1994. She was replaced by Tiffani Thiessen, who played badgirl Valerie Malone.
In 1998 she was cast in the hit television show 'Charmed', in which she played Prue Halliwell, the oldest of three sisters who discover they are witches. She directed several episodes of the show.
She left 'Charmed' at the end of the third season in 2001, reportedly because of tensions with her co-star Alyssa Milano. Although she left the show long before it ended, she continued to own five percent of the rights.
Doherty starred as a regular on the short-lived soap opera North Shore as Alexandra Hudson, and while she was initially cast in TV comedy 'Love Inc', she was dropped just months before its television show.
She later went on to produce and star in her own reality show, 'Breaking Up With Shannen Doherty', in which she did the dirty work for members of the public ? including ending relationships. Understandably, the show was cancelled after only one season.
Doherty set up her own production company 'No Apologies' in 2007, and reprised her role of Brenda Walsh for a number of episodes in 2008's spin-off '90210' for approximately $50,000 an episode.
Doherty was married briefly to George Hamilton's son Ashley; was also married to Rick Salomon and was briefly engaged to actor Judd Nelson.
She was arrested for drunk driving in 2001 and has posed nude for Playboy magazine several times.
Ian Ziering (Steve Sanders)
Ian Ziering starred as Steve Sanders, the spoiled son of Rush and Samantha. He appeared in a number of different projects ? including the 2005 film 'Domino', which starred a sultry Keira Knightley.
Ian also appeared in a number of television programmes ? including 'Jag', 'The Doctors' and 'Guiding Light'. He appeared alongside his 'Beverley Hills' co-star Jennie Garth in the sitcom 'What I Like About You' and had a main role in the videogame 'Freelancer'.
In 2006, Ian produced, directed and starred in the short film, 'Man vs. Monday', which won the Audience Choice Award at the 2006 Ft. Lauderdale Film Festival. Also in 2006, Ian won the Best Actor Award at the 2006 Monaco Film Festival for his portrayal of Francis in the independent film, 'Stripped Down'.
