Jen on Courteney's Cougar Town & More Costars as Guest Stars
COURTENEY COX & MATTHEW PERRY ON GO ON
Though these former Friends are no longer must-see TV, they're still actual friends, as evidenced by Cox's March 2013 guest spot as a love interest on Perry's short-lived comedy Go On.
COURTENEY COX & MATTHEW PERRY, LISA KUDROW & JENNIFER ANISTON ON COUGAR TOWN
And in six seasons, Cox has managed to host most of her Friends on her comedy Cougar Town, including Perry, Kudrow and her IRL best friend, Aniston.
JENNIE GARTH & TORI SPELLING ON MYSTERY GIRLS
In the '90s, Beverly Hills, 90210 had its fair share of on-set drama. But despite the bad blood that brewed between some of the cast members, others really bonded, like Garth and Spelling, who reunited to star in ABC Family's Mystery Girls in 2014, playing former '90s stars who team up to solve mysteries.
THE CAST OF SEINFELD ON CURB YOUR ENTHUSIASM
Seinfeld wouldn't have been Seinfeld without Larry David's witty writing. And though he'd been against reuniting the show's hilarious cast on his own show, Curb Your Enthusiasm, he caved in series' seventh season (2009). In the episode, his alter ego wrangled the foursome back together in order to win the affections of his estranged wife. But it was definitely a one-time deal: "It's not a reunion show, but it's the closest you'll get," he said.
SEAN HAYES & DEBRA MESSING ON SMASH
It took seven years, but Hayes and Messing's first on-screen reunion since Will and Grace, when Hayes had a three-episode run on Messing's show Smash as a TV actor heading to Broadway, was theatrical, dramatic and well worth waiting for – though the two never shared a scene.
RAY ROMANO & PATRICIA HEATON ON THE MIDDLE
When Everybody Loves Raymond's Heaton landed on a new sitcom, The Middle, a visit from her former fictional other half was a given. It came in the form of a 2011 season premiere spot, when he appeared as a one-time friend who'd crashed Heaton's character's honeymoon.
LISA KUDROW, DAVID SCHWIMMER, MATTHEW PERRY, COURTENEY COX & MATT LEBLANC ON WEB THERAPY
Proving once again how everlasting the bonds of Friends are, all of the cast members except Aniston have appeared on Kudrow's cult fave Web Therapy for multi-episode arcs.
ZACH BRAFF & DONALD FAISON ON THE EXES
As any Scrubs diehard will tell you, the show's two male leads are best friends both on- and off-screen. So when Faison landed on the TV Land sitcom The Exes, Braff was first on the list of dream guest stars. Said appearance aired in the middle of the show's second season in 2012, when Braff played Faison's unruly client and house guest.
BJ NOVAK & MINDY KALING ON THE MINDY PROJECT
On The Office, Novak and Kaling's Ryan and Kelly were the hardest Dunder Mifflin couple to keep up with, constantly on again and then off again. Fact mirrored fiction when the two started seeing each other in real life, and although they're no longer a couple, they're still tight, as evidenced by Novak's romantic story arc on Kaling's latest sitcom, The Mindy Project.
SETH GILLIAM, CHAD COLEMAN & LAWRENCE GILLIARD JR. ON THE WALKING DEAD
The reunion of The Wire's Gilliam, Coleman and Gilliard Jr. on The Walking Dead happened by the wishes of a higher power: the show's creator, Robert Kirkman, who told Business Insider that it was his love for the critically acclaimed show that led him to get the trio together again. "I think that every actor that's been on The Wire is absolutely fantastic," he said.
TINA FEY & AMY POEHLER ON 30 ROCK
They're comedy's favorite female duo, and with a friendship that's spanned decades (and three Golden Globe hosting gigs), Poehler and Fey regularly crash each other's professional projects. While Poehler's part on 30 Rock was small (she played a teenage Liz Lemon for all of 30 seconds in 2012), it was obvious that there isn't an actress in Hollywood better equipped to take on Fey's younger self than her former SNL costar.
TITUSS BURGESS, JANE KRAKOWSKI & TINA FEY ON UNBREAKABLE KIMMY SCHMIDT
For a few years running, 30 Rock was the darling of the comedy world (Fey's got plenty of Golden Globes and Emmys to prove it). So when she was looking for faces to fill her new Netflix series, she turned to two of her past colleagues, Krakowski and Burgess, who helped lead Unbreakable Kimmy Schmidt to critical acclaim in early 2015.
