We’re beginning to think Once Upon a Time is a breeding ground for fairy-tale romances. First, Josh Dallas and Ginnifer Goodwin take their Prince Charming-Snow White lovefest into the real world, and now People is reporting that another pair of OUaT co-stars are heating up off the small screen.

According to the mag, Once Upon a Time star Jennifer Morrison, 33, and recurring cast member Sebastian Stan, 28, are an item.

"They met on set and are now exclusive," a source spilled to People. "They started dating three months ago. They seem to be really happy together, but are trying to take things slow."

Sebastian’s past girlfriends include his former Gossip Girl co-star Leighton Meester and Glee’s Dianna Agron, and Jennifer Morrison was once engaged to her House M.D. co-star Jesse Spencer.

We think they make an adorable couple; do you agree?
