Nick Viall finally got his happy ending on The Bachelor — and he's proving his love for fiancée Vanessa Grimaldi on Jimmy Kimmel Live.

Fresh off their engagement, the couple headed to the late night show where they played "The Newly Engaged" game and made an unexpected sex confession.

"Where did you and your fiancée first make love?" Jimmy, a die-hard Bachelor fan, asked the duo.

"Finland," both answered with huge smiles on their face.

Along with confirming that they made use of the Fantasy Suite on the reality dating competition, Nick, 36, and Vanessa, 29, also proved they know each other pretty well, with matching responses on most of the questions on the makeshift game show.

However, they did admit they still have a lot to learn before walking down the aisle.

"We haven’t even made a dinner reservation yet," Nick said when asked about marriage.

Nick got down on one knee after four seasons on reality television and chose the special education teacher over runner-up Raven Gates, 25.

"I'll never forget the first moment I started falling in love with you. It was actually just the second rose ceremony…" Nick said before popping the question. "Every moment since then, I've been falling more and more in love with you. There were plenty of times where I tried to fight it and I don't want to fight it anymore. I do love you, I'm in love with you."

Next up for Nick: Dancing With the Stars, where he will compete for the mirror ball trophy with his partner Peta Murgatroyd.
