AceShowbiz - It seems like Scott Disick's brief stint in rehab greatly affects his girlfriend Sofia Richie. While the 21-year-old model has yet to break her silence on the matter, she recently took to her Instagram account to share a new selfie.

Seemingly taken at her home, the Thursday, May 7 picture featured the daughter of Lionel Richie looking at the camera with sad eyes. Sofia, who opted for a minimal makeup, had her arms in front of her atop a chair and rested her chin upon them. Although she only had some light nude gloss over her lips as she left her hair wet, the blonde beauty looked stunning as usual.

"Thursday's are... exciting," so Sofia wrote in the caption.

In related news, Sofia was reportedly worried after Scott checked out of rehabilitation with a report saying that the 36-year-old flew to Colorado from Los Angeles on Tuesday, April 28. "Sofia noticed a change in him and that he wasn't as healthy and happy as he could be and Scott made the decision to get help for himself and for her and their relationship," a source said to Us Weekly.

As for the "Flip It Like Disick" star, he was said to be "really hurt, annoyed and upset at the fact that his privacy was violated when all he was trying to do was something that was good for himself and to better himself since he noticed he was going down a slippery slope."

"It's a very sensitive situation and Scott felt he needed to get out of there and leave right away once he found out they leaked everything," the source said. "Him and his lawyer are planning to take serious action against the facility."

According to previous reports, Scott had been struggling with trauma from his past. News of his rehab stint broke after his photo of him joining a Zoom group meeting at the All Points North Lodge made its way out online, prompting the TV star to threaten to sue the rehab facility for violating his privacy.
