Some of Sofia Richie's most recent photos are causing some buzz on the interwebs. Since the 20-year-old is a model, her following is used to seeing her strike poses but her latest over-the-shoulder gaze pic displays a noticeable change in her frame.

The aspiring singer uploaded a pic of herself sporting form-fitting casual wear. The one-piece accentuated her rump in a way that inspired some social media users to speculate about plastic surgery as if fitness was a thing of the past. Some noticed that her "Kardashian booty" picture seemed to feature the same kind of background that Kylie Jenners uses to shoot photos at her house.

Sofia has indeed been spending time with the Kardashians, especially considering her relationship with Scott Disick, according to People. Since her boyfriend is co-parenting with his former partner Kourtney Kardashian, the three of them meet up at times to make sure they're all on the same page when it comes to the children. 

“Sofia spends time with Kourtney’s kids, so Kourtney wants to make sure they are all on the same page. Scott and Sofia tend to get into arguments. Kourtney wants to make sure the kids are in a positive environment when they are at Scott’s house. She is setting up rules for how things need to be when the kids are with Scott.”
