Kaitlyn Bristowe and Jason Tartick’s flirtation appears to be a full-fledged romance now. Bristowe, who was a contestant on season 19 of The Bachelor and the star of season 11 of The Bachelorette, surprised Tartick with a visit to Seattle and publicly called herself his girlfriend on Instagram.

On Thursday, January 17, Tartick posted an Instagram story of a night out with his friends. In the black-and-white video, the banker and season 14 Bachelorette contestant introduced his followers to his crew, saying, “There’s my boy Nate, he’s on the phone with his sweet girlfriend. And there’s Derek. And there’s me, drinking a little —.” Before he could finish his thought, Bristowe popped up next to him, wrapping her arm around him and piping in: “With his sweet girlfriend!” Not to be outdone, he immediately joked back, “Where’d you come from?”

And the cuteness didn’t end there. The caption for the video included tags for Nate and Derek, plus this shout-out to Bristowe: “Who’s that girl… @kaitlynbristowe. #BestSurprise.”

The Bachelor Nation alums were first caught flirting on Bristowe’s Off the Vine podcast in early January, a couple of months after she announced the end of her three-year engagement to Shawn Booth in November.

“Sometimes you need to take a moment and take a step back to think about what you are fighting for and if it make sense for your long-term happiness,” she said at the time.

It seems that long-term happiness may come courtesy of Tartick.
