That didn't take long!

Kourtney Kardashian and Younes Bendjima were back together last night, as they hit the grocery store and documented their trip on social media. Speaking of social media, the two prompted breakup rumors with their Instagram activities earlier this week.

The mother-of-three unfollowed her 24-year-old boy toy, and then he made his account private before deleting it entirely. Now, she's back following him, and he's back online, and they're back to hanging out. We wonder what must have happened?

Their reconciliation probably comes as a blow to Scott Disick, who was undoubtedly hoping his baby mama was single again so he could ditch Sofia Richie and put his family back together.

"Scott is still insanely jealous of Younes. He just can't come to terms with the fact that Kourtney has found true happiness with someone else," a source told E! News.

"It makes things between them tense and unpredictable. Kourtney never knows when he is going to fly off the handle or go nuts about something. Scott just never thought it would last this long with Younes or become so serious. Nobody really did. Scott is hurt she chose someone else and it really bothers him. He can't control his emotions about it and lets it all out," the source added.

Does Kourt really think this romance is going to last?! She should just cut her losses and get back with The Lord!
