WHOA. We were pretty sure Matt and Rebekah would hook up on their European road trip, but we weren't expecting them to bring in a third party!

In The Vampire Diaries Season 4 finale, “Graduation”, Klaus’ beautiful sis offered to show Matt the world, and the two made plans to tour Europe together over the summer. The lusty kiss that followed convinced us these two were definitely going to explore more than the tourist sites! And we were right.

Executive producer Julie Plec told MTV’s Hollywood Crush that the couple will be joined by a “mysterious” Russian beauty named Nadia for a bedroom tryst! Plec said we’ll get to see the hot hookup in flashback when season 5 starts up, adding, “... we get to see a nice little moment, in quotes—define it as you like—where Rebekah and Matt are living life to its fullest in Prague."

To the fullest, indeed. But sorry, Matt and Rebekah ‘shippers. Their relationship won’t continue. Julie also told MTV that, "Matt promised Rebekah at the end of the season that what happens on the road stays on the road. So they get a great experience and a great adventure, and then when all is said and done and they part, it's very sweet and a nice button to the time that they had together."

Which makes sense, because Rebekah’s gotta pack up and head to New Orleans to join her fam on The Originals this fall. Claire Holt promises the steamy scene will please ALL their fans, saying, "The boys are going to love it; the girls are going to love it; and it was a lot of fun. [Matt and Rebekah] got to explore the world together, and now they're moving on with their lives. I think they both realize it was a mutually beneficial relationship and it was going to run its course, and it will. In a sexy, fun way."

Even better, Julie hinted at another Season 5 spoiler by spilling that the threesome scene won’t be the last time we see Nadia! Plec said, "She will find her way to Mystic Falls under mysterious circumstances and with a mysterious agenda, and she will be providing a lot of story conflict and it will be very exciting. I think that in the beginning she's got a mystery attached to her that brings her into play with Matt a lot, but not necessarily romantically—and then as we move forward we'll see."
