Just the mere mention of '90s primetime soap 'Beverly Hills, 90210' will get that infectious theme song stuck in your head. Dylan, Brenda, Kelly, Brandon and the rest of the original cast -- where are all of the actors who played them now?

Jason Priestley (Brandon Walsh)

Then: After previously appearing on '21 Jump Street' and 'Airwolf,' Jason Priestley played heartbreaker Brandon Walsh, who moves to Beverly Hills with his sister Brenda when their father gets a job transfer.

Now: After Priestley exited the cast in the ninth season, he stayed on as a producer and directed some episodes. He recently appeared on eps of 'Psych' and 'How I Met Your Mother.' In his free time he drives race cars and raises his two daughters with his wife, makeup artist Naomi Lowde.

Shannen Doherty (Brenda Walsh)

Then: Doherty first made a name for herself in films like 'Girls Just Want to Have Fun' and 'Heathers' before signing on as the trouble-making Brenda Walsh on 'Beverly Hills, 90210.'

Now: Shannen left the show after only four seasons, going on to star in three seasons of the WB witchcraft series 'Charmed' before reprising her role as Brenda on the recent CW reboot, '90210.' After some messy personal travails, she's now married to Kurt Iswarienko, and their nuptials were chronicled on the reality series 'Shannen Says.'

Then: A then-unknown actress, Jennie Garth appeared on a single episode of 'Growing Pains' before nabbing the role of Kelly Taylor, the girl who goes from spoiled sexpot to mature and reasonable adult.

Now: Garth starred in several made-for-TV movies before reprising the role of Kelly on the new '90210' series on the CW. In 2012, she had her own reality show on CMT called 'Jennie Garth: A Little Bit Country,' and she recently divorced fellow actor and 'Twilight' star Peter Facinelli.

Now: His role on 'Beverly Hills, 90210' made him a total '90s heartthrob and earned him roles in the 'Buffy the Vampire Slayer' movie and the HBO drama series 'Oz.' Recently, he's appeared on episodes of 'Body of Proof' and 'Community.'

Tori Spelling (Donna Martin)

Then: We saved the best for last. Tori Spelling, daughter of 'Beverly Hills, 90210' producer Aaron Spelling, played Donna Martin, the pure teen queen who doesn't want to have sex until she's married.

Now: After starring in some TV movies, Spelling went on to find success in the reality television game with 'So NoTORIous' and a string of shows with her husband Dean McDermott, with whom she has four children. But since Tori and Dean met and began their relationship while they were both still married to other people, they're tabloid staples (whether they want to be or not).
