Can co-star couples really last in Hollywood once the cameras stop rolling?

The Voice fans everywhere were shouting "I knew it!" when it was confirmed that coaches Gwen Stefani and Blake Shelton are officially dating. Soon after that initial excitement, of course, came the worry every TV fan has when they learn two stars from their favorite show have entered a romantic relationship: What happens if they break up?! Fortunately for fans of the NBC reality hit, we have some good news: There are co-stars-turned-couples that have managed to make it work while working together. 

We've rounded up 11 co-star couples who have stood the test of time, so grab a paper and pen, Gwen and Blake, and start taking notes!

Once Upon A Time, Josh Dallas, Ginnifer Goodwin

ABC

Josh Dallas and Ginnifer Goodwin: Sometimes, art really does imitate life! Sparks quickly flew between Prince Charming and Snow White's real-life counterparts on Once Upon a Time, with Dallas and Goodwin becoming a couple soon after the show began in 2011. The couple made it official with a wedding in April 2014, welcoming their first child, soon after in May. And guess what? Goodwin's pregnancy was written into the show, with Snow and Charming also welcoming a baby. Happily ever after indeed. 

Blake Jenner, Melissa Benoist

Kickstarter

Melissa Benoist and Blake Jenner: Sorry, fanboys, but Supergirl is taken. The Glee couple, who met on set when they both joined the Fox series in its fifth season, tied the knot in a secret ceremony this past spring. 

REVENGE, JOSH BOWMAN, EMILY VANCAMP

Josh Bowman and Emily VanCamp: While Daniel ended up shooting Emily on their wedding night on Revenge, Bowman and VanCamp have had a far less dramatic relationship then their on-screen counterparts. The duo began dating during their ABC hit series' first-season run in 2011.

Jared Padalecki and Genieve Padalecki: The cute parents-of-two tied the knot in February 2010 after meeting on the set of his hit CW series, Supernatural, on which she played his love interest/nemesis, Ruby. Fun fact: In a super-meta season six episode, she even played an exaggerated version of herself.

Stephen Moyer and Anna Paquin: It was love at first bite for Moyer and Paquin when they met on the HBO hit vampire series, True Blood. The couple said exchanged vows in August 2010, and welcomed twins Charlie and Poppy in 2012.

Alexis Bledel and Vincent Kartheiser: While her Mad Men character's time on the show came to a tragic end, she left with a real-life happy ending as Bledel and Kartheiser wed in a top-secret ceremony in August 2014. But the duo didn't begin dating until after Bledel finished her run on the show, with Kartheiser saying, "We were completely professional. We never saw each other out. We never—it was nothing, it was just work."

Ashton Kutcher and Mila Kunis: OK, so these two technically didn't become a couple while they were actually working together on That '70s Show (though Kutcher was her first kiss ever!)they began dating in 2012 and things got serious pretty fast. Kutcher popped the question in February 2014, and welcomed their first child in October 2014. Kutcher and Kunis then said "I do" in July. After first meeting in 1998, only to get married 17 years later, we guess it's true for these two: Patience really is a virtue. After becoming a couple, they did work together again: Kunis played a love interest for Kutcher on Two and a Half Men

Alyson Hannigan and Alexis Denisof: Wesley + Willow = OTP?! Hannigan and Denisof became a couple soon after meeting on the set of Buffy the Vampire Slayer, later working together on Angel and How I Met Your Mother. The duo has two children, Satyana and Keeva, together, and renewed their vows in 2013 for their 10-year anniversary celebration.
