He's finally back on daddy duty.

Scott Disick has spent almost every waking moment with Sofia Richie since they began dating this summer, but he took the night off to take kids Mason and Penelope to dinner in Calabasas yesterday evening.

The reality star's new romance with Lionel Richie's daughter has been going well, but when they were in Miami for Art Basel last week, it hit a bit of a snag and they got into a huge spat.

"They were arguing and definitely in a fight. [Richie] wouldn’t even talk to him. He grabbed her neck to try and kiss her, and she wasn’t having it. They ended up leaving," a source that attended the “Kith x Daniel Arsham” event told Page Six.

Still, The Lord is smitten with his lady love, and hasn't felt this way since his relationship with Kourtney Kardashian.

"Scott Disick sees a lot of himself in Sofia [Richie] and that’s why he’s so drawn to her. He’s turned on by the fact that Sofia is a young hustler, a go-getter and she’s super into fashion. It also helps that she’s super beautiful and wise beyond her years. With her partnership deal she was able to land with Adidas, Scott saw that and loved her entrepreneurial prowess that she displayed and not only does that remind him of his younger self, but a younger Kourtney [Kardashian] as well as she’s always shown that she’s willing to do whatever it takes to make things happen for herself and her family,” a source dished to Hollywood Life.

"Scott can never completely erase Kourtney from his memory, but he definitely felt the same way about her when they were younger. He’s almost reliving that emotional high that he had with Kourtney and Sofia has been the perfect companion for him. Always by his side and there when he needs her the most. Scott has never been shy about displaying his love of business and money, and with Sofia he knows they can build their own empire one day. Scott has been giving Sofia the game in what it takes to be a successful businesswoman and she’s been really receptive to his advice. He loves the dynamic they share,” the source added.

We wouldn't put it past LD to pop the question sometime soon!
