Just look at that glow (and the sly smile) on her face!

On Tuesday Kourtney Kardashian took Mason to art class in Calabasas, and she definitely had an extra spring in her step. As you know, she JUST got back from a romantic vacation with baby daddy Scott Disick in Cabo San Lucas, Mexico over the weekend, and it seems like the two 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 People. “He surprised her and whisked her away on this trip. They seem very close and happy." Scott shared a sexy snapshot of Kourt's butt in the pool on Sunday and simply captioned the pic, "Views." She also posted the same pic on her Insta as well.

How long will this reconciliation last though? She may be happy right now, but can't even begin to count the ways Scott has been a sh*thead to her over the years!
