Scott Disick and Kourtney Kardashian traveled south of the border to Cabo San Lucas, Mexico over the weekend, and a source tells People that the duo are definitely back on.

“Scott set it all up and [it] was a way to try and make things work again with Kourtney,” a source told the mag. “He surprised her and whisked her away on this trip. They seem very close and happy."

Scott shared a sexy snapshot of his baby mama's booty in the pool on Sunday and simply captioned the pic, "Views." She shared the same shot with the same caption, though his was cropped in a bit more on her butt. Glad they're able to focus on the important stuff!

Though the two have been pretty on and off since splitting in 2015, Kourt dished to Cosmopolitan earlier this year that she wasn't sure where things stood with her sexy but troubled baby daddy. “The idea of having my family together is amazing, but it’s not the way things ended up," she said. "They may end up there. I’m not sure. To me, it’s in God’s hands. If it’s meant to be, then things will line up. We definitely tried for a long time. But relationships are exhausting! Being able to focus on the kids and me right now is good. We say to each other all the time, ‘I’m the coolest ex-girlfriend/baby mama you could ever ask for!'”
