BEVERLY HILLS, 90210
For Jennie Garth, the former Kelly Taylor of Beverly Hills, 90210, celebrating a 40th birthday with ex-costars Shannen Doherty and Ian Ziering in West Hollywood last week helped take the sting out of a sadness-filled year. "There's always that 'where are they now' thing," Ziering said of Garth, who's starring in her own reality show. "I had the honor of working with her for 10 years, and every day was better than the one before."

In November 2010, 15 years after Full House ended its run, Mary-Kate Olsen and Ashley Olsen proved they were still Daddy's girls when they attended a benefit thrown by TV pop Bob Saget. Afterward, Saget said he was overwhelmed to have them show their support, adding, "The joke I have with them is that I diapered them. They were 3 months old and doing the show, and I also had a baby, and there was a time when I knew how to diaper them really quickly. Of course, I had permission."

MY SO-CALLED LIFE
Angela Chase and Jordan Catalano faltered on their road to romance amid the '90s high-school angst of My So-Called Life, but Claire Danes and Jared Leto look like they've moved on – especially fashion-wise. The former costars, who still keep in touch, were photographed in 2010 at the Elle Fashion Awards in London. "He's honestly not any different from when I first met him," Danes, now starring on Showtime's Homeland, told StyleList about the Thirty Seconds to Mars frontman. "Now he's like a full-fledged rocker, but his personality has always been eccentric. Now he just has more reason to express that eccentricity."

SAVED BY THE BELL
In 2009, Saved by the Bell cast members Lark Voorhies, Mario Lopez, Tiffany Thiessen, Mark-Paul Gosselaar and Elizabeth Berkley reunited – sans Screech (Dustin Diamond) – for a PEOPLE shoot 15 years after they'd turned in their locker combinations at Bayside High. "We're still very close for a cast that's known each other 20 years," said Gosselaar, now starring in TNT's Franklin amp Bash. "I think that will continue."

THE FRESH PRINCE OF BEL-AIR
Late last year, Will Smith gave a Facebook shout-out to his humble beginnings by posting a photo of his reunion with most of the cast of The Fresh Prince of Bel-Air, the '90s sitcom that catapulted him to stardom. "There's nothin' like spending Holidays with fam," Smith – posing with Tatyana Ali, Karyn Parsons, Alfonso Ribeiro and James Avery – wrote about his costars, who gathered to support a charity founded by Parsons.

On Roseanne, Johnny Galecki and Sara Gilbert ended up married, but in real life the costars dabbled in dating before going their separate ways, romantically speaking. Still, that didn't stop the longtime friends (seen here in 1995 and 2008) from reminiscing about the old days – and their onscreen reunion on The Big Bang Theory – when Galecki appeared on Gilbert's The Talk. "I was more nervous about our kiss on Big Bang Theory than I was on Roseanne," Galecki confessed to Gilbert. "You're the only person who can gauge if I'm improved as a kisser over the last 20 years."

MARRIED ... WITH CHILDREN
Ed O'Neill and Katey Sagal gleefully stomped all over the ideal of a warm 'n' fuzzy TV family as the heads of Married … with Children's raunchy, tasteless Bundy clan – and America loved it. Twenty-four years after the show's 1987 debut, O'Neill was reunited with his former on-screen wife when he was honored with a star on the Hollywood Walk of Fame. "I spent 11 years laughing hysterically every day," Sagal said. "I just always thought he was the funniest guy on television."

The show that saw future Wall Streeter Alex P. Keaton (Michael J. Fox) clashing with hippie parents Elyse and Steven (Meredith Baxter and Michael Gross), Family Ties ended its run in 1989 – but barely a year seemed to have passed when the crew, including Justine Bateman, Tracy Pollan and Tina Yothers, reunited for the 2011 TV Land Awards. "We knew how lucky we were ... and that we caught lightning in a bottle," Fox told the audience on accepting the Fan Favorite Award. "The fact that we can still enjoy it 30 years later is a blessing that we can't thank you enough for."

FACTS OF LIFE
You take the good, you take the bad – and you take a lot of hair spray – when attending boarding school in Peekskill, N.Y., in the '80s. Twenty-three years after Facts of Life bowed in 1988, Kim Fields, Lisa Whelchel, Nancy McKeon, Mindy Cohn, Charlotte Rae, Geri Jewell and Cloris Leachman had no trouble picking up right where they left off in a 2011 Good Morning America interview. When Cynthia McFadden admitted she was surprised that on-screen frenemies McKeon and Whelchel became roommates after the show ended, McKeon replied: "We've always been friends. It was a character." Added Whelchel: "We were just acting!"
