She takes care of her man!

Sofia Richie stopped to put gas in boyfriend Scott Disick's Bentley last night, and the model kept it casual in sweatpants that clung to her model bod. Even in casual clothes she's a total knockout!

Lionel Richie's daughter and the reality star have lasted longer than anybody anticipated, and his ex Kourtney Kardashian is finally coming around to the idea of her being a permanent fixture in their kids' lives. It took them living together to make it happen, though!

"Sofia moved in with Scott this past summer. Scott and Kourtney discussed his plans on living with Sofia before they made it official. Scott could tell Kourtney was a bit jealous at the time, but more so concerned of the fact that their kids would be sleeping there while Sofia lived there, too. She wanted to make sure they were in good hands," a source dished to Hollywood Life.

"After Scott and Sofia had been living together for a few months, Kourtney and Scott felt it was best for all three of them to meet up together since their kids would be spending the night there on a regular basis. That’s when they all went to dinner together in November. It was important for Scott that Kourtney felt comfortable with Sofia and got to meet her, so she could see for herself that Sofia truly does care about, and treat their children amazing," the source added.

We have a feeling there might be wedding bells in 2019 for The Lord and his lady!
