Scott Disick had the funniest reaction to Sofia Richie's latest sexy Instagram post

Scott Disick is a fan of girlfriend Sofia Richie's latest Instagram post.

The model, who just turned 21 in August, took to the social media platform on Thursday to post a photo of herself wearing nothing but high-waisted jeans. In the sultry snap, Richie hugs her chest in order to not show off too much skin as she looks directly into the camera.

How’s your Thursday?

A post shared by Sofia Richie (@sofiarichie) on Oct 10, 2019 at 3:37pm PDT

"How's your Thursday?" she captioned the post nonchalantly.

Well, for her 36-year-old boyfriend, the photo certainly improved his day -- at least judging by the comment he posted on her photo.

"It’s not bad thanks," the "Flip It Like Disick" star responded.

The playful exchange on Instagram comes less than a week after Richie made her official debut alongside Disick on "Keeping Up With the Kardashians." In the episode, Disick's ex, Kourtney Kardashian, 40, with whom he shares three children, invites Richie to their family trip to Finland in an effort to let her know that she's welcome into their family.

Sofia Richie and Scott Disick were first romantically connected in May 2017, making their relationship Instagram official several months later, in October 2017.
