Kourtney Kardashian and Scott Disick have gone through their ups and downs, but things continue to seem all fine and dandy between these exes.

The E! star took to Twitter to wish her ex-boyfriend a happy birthday, while also giving fans one epic throwback  photograph of the couple to really make it worthwhile. Posting a photo of young Scott lying down on a couch (and flipping the bird) while Kourt casually sits on top of him in a bikini, the celeb simply writes, "Happy birthday baby daddy!"

Scott's bestie, Khloe Kardashian, also sent well wishes to the birthday boy on social media, posting a photo of the pair on Instagram with the caption, "Happy birthday lord!!! We've been through it all and I wouldn't have it any other way! Forever my brother and forever my bestie! Love you."
