Then: She was America's golden girl in 1992, taking home the gold medal at the Winter Olympics in Albertville, France, before going pro.
Now: All those double-axels are paying off! Yamaguchi – paired with professional hoofer Mark Ballas – has proved herself to be a serious contender on this season of Dancing with the Stars, earning the only perfect 30 from the judges this season. Will she add the "mirror ball" trophy to her case?
Then: It was the show that launched a thousand sideburns. After its debut in 1990, this FOX saga about the oh-so-rich teens at fictional West Beverly High School set trends (chokers, anyone?) and turned Jason Priestley, Shannen Doherty and Luke Perry into instant stars.
Now: A spinoff of the series is in the works. Expect some familiar faces and names – some new West Beverly students will be relatives of the former Peach Pit crowd. And star Tori Spelling – whose dad Aaron produced the original – has already said she'd love to be in the remake.

Then: The exploits of Elizabeth and Jessica Wakefield came to life in 1994 when Doublemint twins Brittany and Cynthia Daniel starred in a TV show based on the popular books. The sisters also posed for revamped versions of the book covers.
Now: They're ba-ack! Random House is re-releasing the series – with All My Children's Leven Rambin posing as the twins. That's not the only change – the girls' red Fiat will reportedly become a Jeep and "good twin" Liz will work at a Web site, not the school paper. But will Bruce still have a "1Bruce1" license plate?
Then: The choreographer turned pop star topped the charts in '91 with "Rush Rush" – remember its Rebel Without a Cause-inspired video, costarring Keanu Reeves? Her love life also made headlines, when she married and later divorced Brat Packer Emilio Estevez.
Now: The American Idol judge is straight up returning to her roots! Abdul unveiled "Dance Like There's No Tomorrow" – her first single in 15 years – at the Super Bowl. The track will appear on fellow Idol judge Randy Jackson's compilation, Randy Jackson's Music Club, Vol 1. No word yet on MC Skat Kat's cooperation.

Then: Grunge ruled – in music and in fashion. Seemingly everyone had a Smashing Pumpkins CD in their Discman and an oversized plaid flannel shirt wrapped around their waist – think Bridget Fonda in 1992's Singles (far left).
Now: Hollywood trendsetters – like Mary-Kate Olsen and Miley Cyrus – are mad for plaid! To keep the look current, Olsen updates it with skinny jeans and necklaces.
Then: They were arguably the biggest group, with a No. 1 single ("Step by Step"); a No. 1, triple-platinum disc (also called Step by Step); a Saturday morning cartoon show, Magic Summer; an extravagant tour; and a pay-per-view special that broke records.
Now: It's time for more of the right stuff. Danny Wood, Jordan Knight, Joe McIntyre, Donnie Wahlberg and Jonathan Knight have reunited for screaming girls everywhere. Up next: A new album and tour. They're still hangin' tough!
