Mad Men star Vincent Kartheiser and one-time guest star Alexis Bledel got married in a secret ceremony earlier this Summer, and it's not just cute because these two are adorable together — it's cute because they played love interests on the AMC drama. They're not the only couple for whom sparks have flown after the cameras stopped rolling, like these movie couples who dated in real life . Over on TV, there are pairs we'll never forget (Seth and Summer!) and those you may not have even known were together (yes, Felicity and Ben were really an item), so check out these other TV couples who were together both on and off the small screen.

Lisa Rinna and Harry Hamlin
Lisa Rinna and Harry Hamlin were both on the long list of famous guest stars on Veronica Mars . The real-life married couple played Logan's parents on the detective series. Too bad their onscreen marriage wasn't as successful as their real one!
Blake Lively and Penn Badgley
Gossip Girl's other golden couple, Serena and Dan, have several breakups and makeups over the series's run, but they ultimately end up together. While Blake Lively  and Penn Badgley  also fell in love in real life a few years ago, their romantic destiny never led them back together.
Emily VanCamp and Josh Bowman
Their onscreen relationship is fraught with deception on Revenge, but there appears to be far less drama in the real-life romance of Emily VanCamp and Josh Bowman.
Keri Russell and Scott Speedman
Felicity (Keri Russell ) was always torn between her love interests, Noel and Ben, but in real life, she chose Ben — well, the guy who played him, anyway. Scott Speedman  and Russell dated while the series still aired in the early 2000s.
Ginnifer Goodwin and Josh Dallas
How sweet is this: not only do Ginnifer Goodwin  and Josh Dallas play a romantic-sounding couple on TV (Snow White and Prince Charming), but they're in love in real life, too — they just got married  and had their first child! What a fairy-tale ending.
Nina Dobrev and Ian Somerhalder
They're an one-and-off scorching-hot vampire couple on The Vampire Diaries (it's really complicated), and Nina Dobrev  and Ian Somerhalder  were scorching hot in real life until last year. We'll always have Mystic Falls.
Adam Brody and Rachel Bilson
We still think of Seth and Summer as one of our favorite TV couples, and it was even sweeter when Adam Brody  and Rachel Bilson  dated in real life. But now Seth is married to Blair , and my brain is exploding.
Chad Michael Murray and Sophia Bush
They were passionate high school couple Lucas and Brooke on One Tree Hill, and that passion carried over into a romance and eventual marriage for actors Chad Michael Murray and Sophia Bush. But unfortunately, much like their characters on the show, it wasn't meant to be, and they split up.
Jennifer Morrison and Jesse Spencer
The House M.D. costars dated on the show and tied the knot, too. But while their real-life counterparts also got engaged, they didn't make it to the altar.
Kat Dennings and Nick Zano
On 2 Broke Girls, Max and Johnny have a complicated flirtation, but in real life, Kat Dennings and Nick Zano are a solid couple.
Alexis Bledel and Vincent Kartheiser
Their Mad Men love story isn't so romantic — Pete and Beth both cheat on their spouses — but in real life, Vincent Kartheiser and Alexis Bledel's situation lacks the scandalous aspect, and they secretly tied the knot this Summer.
Leighton Meester and Sebastian Stan
On Gossip Girl, Carter Baizen romances both Blair and Serena, but he has more of a legitimate relationship with Serena. However, the real-life legitimate relationship was between Leighton Meester  and Sebastian Stan, who dated for a couple of years while the show was still on.
Mila Kunis and Ashton Kutcher
It's almost too perfect that Jackie and Kelso are together. We loved their on-and-off relationship on That '70s Show, but we're glad their current pairing has led to an engagement!
Anna Paquin and Stephen Moyer
Bill and Sookie's vampire/human love affair isn't going so well for them on True Blood, but outside of Bon Temps, things are going quite well for Anna Paquin  and Stephen Moyer  — the married pair now have a couple of kids. I still wonder if he calls her "Sookeh" at home.
Amy Poehler and Will Arnett
Arrested Development's George — aka "Gob" — marries a seal dealer who eventually joins the army to avoid her feelings for Gob's brother-in-law, Tobias . The quirky duo is played by then-married couple Will Arnett  and Amy Poehler , who started dating in 2000, got married in 2003, and announced their separation in September 2012.
Jerry Ferrara and Jamie-Lynn Sigler
On Entourage, Turtle doesn't have the easiest time catching the ladies' attention — until he starts dating Jamie-Lynn Sigler, who plays herself. After her guest-starring role in 2008, the couple stayed together off screen until 2009.
Jason Segel and Linda Cardellini
In the cult hit Freaks and Geeks, Nick — one of the freaks — can't help but pour all his energy into Lindsay. In real life, Jason Segel  and Linda Cardellini ended up dating for a few years after the show was canceled.
Alexis Bledel and Milo Ventimiglia
Fans loved the dramatic relationship between Rory and Jess on Gilmore Girls, and apparently there was something real about that onscreen chemistry — Alexis Bledel and Milo Ventimiglia  dated for four years between 2002 and 2006.
Jennifer Garner and Michael Vartan
On screen, Alias characters Sydney and Michael worked together as part of a top-secret branch of the CIA. There was nothing secret about Jennifer Garner  and Michael Vartan's offscreen romance, though — the pair dated for a little over six months in the wake of her 2003 divorce from Scott Foley.
Melissa Benoist and Blake Jenner
Her character Marley may have chosen another guy over him on Glee, but in real life, Blake Jenner is the one that Melissa Benoist wants. The pair quietly dated and surprised everyone when they got engaged last Summer.
Rose Leslie and Kit Harington
Ygritte and Jon Snow fall in love in season three and then break up, Game of Thrones style — she shoots him full of arrows. Rose Leslie and Kit Harington dated previously, broke up, but appear to be back on , and we sincerely hope there are no arrows involved.
