Then: Crawford hit her peak during the '90s, hosting MTV's "House of Style" and becoming briefly hitched to Richard Gere. She also tried her hand at movie stardom, costarring with William Baldwin (he's the good-looking, bland Baldwin) in the middling 1995 action caper "Fair Game."
Now: Though no longer the mega-star she once was, Cindy continues to endorse products like her new line of home furnishings for JC Penney. Now 43, Cindy reminded everyone she's still got it by covering herself in shaving cream and posing nude for a recent issue of "Allure."
Then: As "Beverly Hills 90210"'s Kelly Taylor, Garth was the most wholesome of the bunch (even when her character was downing diet pills and suffering assorted dramas). Her feud with costar Shannon Doherty was the stuff of legend and resulted, according to Tori Spelling's autobiography, in a knock-down, drag-out fistfight. (Though both parties deny it.)
Now: After starring opposite Amanda Bynes in the sitcom "What I Like About You" (and participating in the new C-list celebrity rite of passage, "Dancing with the Stars") Garth returned to the role that made her famous on CW's new "90210" opposite old rival Doherty. It's amazing how time (and a reported $50K per episode) can mend broken fences.
Then: As "Saved by the Bell"'s wholesome Kelly Kapowski, and "Beverly Hills, 90210" vixen Valerie Malone, Thiessen ran the crush gamut during the '90s and ensured her place in the hearts of teenage boys with a penchant for oft-preachy youth programming.
Now: Now just Tiffani Thiessen, the actress had a resurgence in recent years on the short-lived series "Fastlane" (yep, that show where she made out with Jamie Pressly) and ABC's "What About Brian." Sadly, both shows crashed and burned, just like Thiessen's film career. (Her turn in Woody Allen's "Hollywood Ending" didn't exactly transform her into Scarlett Johansson.) Recently, Thiessen was cast in the USA pilot "White Collar," and appeared in something called "Cyborg Soldier." Oh, Tiffani. Maybe it's time to give Fallon a call.
Kellie Shanygne Williams
Then: As the object of Steve Urkel's affection for nine seasons on "Family Matters," Williams had plenty of time to perfect her eye rolls and sarcastic quips. An underrated member of the TGIF stable, Williams has comedic timing in spades. Plus, anyone who puts up with Urkel's shenanigans for that long deserves our respect.
Now: After stints on "Eve" and "Moesha," Williams moved back home to start up a fine arts program for kids at Washington, D.C.'s Howard University. Lately she's turned up as the host of Style Network's "Clean House," and can soon be seen in "Steppin: The Movie" opposite old "Family Matters" pals Darius McCrary and Reginald VelJohnson. Hey, she's doing better than that "Family Matters" cast member who went into porn and ended up on "Celebrity Rehab."
Then: While "Clueless" made Silverstone the Reese Witherspoon of her day, guys who hit puberty during the mid '90s will always hold a candle for the "bad girl Alicia" of Aerosmith video fame. Sure, the videos are more than a little silly now (especially "Amazing" and its dated virtual reality theme) but they were also a lot of fun, and an excuse to get Silverstone into various tight outfits. If that meant listening to Aerosmith in bombastic ballad mode, so be it.
Now: Alicia's star dimmed for a time thanks to duds like "Batman & Robin" and "Excess Baggage," and her refusal to accept roles in everything from "Romeo + Juliet" to "Scream 3." She attempted a comeback on TV in the early '00s with the short-lived dramedy "Miss Match," but soon returned to supporting roles in movies like "Beauty Shop" and "Stormbreaker." Currently Alicia is filming the porn satire "Elektra Luxx," and is in talks to appear in a "Clueless" sequel. Come on, you, like, totally knew it was coming.
