She must be glad to have her little girl back!

Kourtney Kardashian and daughter Penelope matched their blue outfits on a playdate in West Hollywood yesterday, and the reality star is back on parenting duty after her kids went on vacation to St. Barths with her ex Scott Disick and his teen girlfriend Sophia Richie.

The Lord held out hope that his baby mama would eventually come back to him, but he's now accepting the fact that she's moved on with boyfriend Younes Bendjima, and he's happily coupled up with Lionel Richie's daughter.

"Scott and Kourtney are on better terms. He was hung up on Kourtney forever and really wanted to make that relationship work, but he’s finally come to terms with the fact that she’s moved on. He’s not partying like he was just a year ago and seems to be in a healthier place mentally and physically. Everyone in the family is really happy with how he’s doing lately," a source told People.

"Scott and Sofia have a super solid relationship and seem really happy together. The kids are allowed to spend time with her. Sofia likes having them and helps Scott. So far, the kids are giving Kourtney good reports about Sofia," the source added.

We guess it is possible to find a happy ending, even if you end up with different partners!
