First came CO Bennett and Daya, then CO Coates Donuts and Pennsatucky, but outside of Litchfield, there's a guard-inmate relationship that Orange Is the New Black fans are swooning over. Dearest reader, we have a feeling you'll do the same. CO McCullough (Emily Tarver) and season six's newest bad girl, Daddy (Vicci Martinez), might seem like an unlikely match behind bars, but in real life, they're not only dating, but they're in a band together!

"We are super in love," Vicci told The News Tribune, a local newspaper from her hometown of Tacoma, WA, about her relationship with her costar. "And we have a music group together. I've started to do music again. She's fulfilling my fantasy of doing duets together."

For Emily's birthday last month, Vicci posted a photo kissing her girlfriend with a caption that could melt even the coldest of hearts. "Happy Birthday to the woman of my dreeeeaaammmzzzz!!! Love? Unconditional. With you, I'm alive," she wrote. "Thank you for sharing your heart and your life and your joy and your funny and your everything!!! I love you #EmilyAnneTarverTheThird @emilytarver Ur my best friend."

Although we don't see them together in the hit Netflix series — Vicci's Daddy is preoccupied with a drug shortage and winning over Daya, and Emily's McCullough is struggling with post traumatic stress disorder following the riot — it's their offscreen love that is giving season six sweethearts Caputo and Fig a run for their money. It appears that Vicci and Emily met on the set of OITNB, which was Vicci's first major acting role. The rest was history!

This isn't the first time a relationship has started on the set of OITNB, either. Samira Wiley (Poussey Washington) and series writer Lauren Morelli started dating in 2014 in Litchfield territory and later tied the knot in March 2017. But if you're obsessed with Vicci and Emily, you'll have to compete with Linda from Purchasing (Beth Dover) to be the couple's ultimate fan, because she's close friends with Emily and loves supporting the couple! Read on to see their sweetest photos together and even some amazing videos of them singing.
