Scott Disick holidays with ex Kourtney Kardashian following reports he and girlfriend Sofia Richie are on a break

Reality star Scott Disick and model Sofia Richie are reportedly taking a break from their relationship once again.

The new development comes just one month after the pair rekindled their two-year romance over the Fourth of July weekend. But now it appears Disick, 37, and Richie, 21, have again hit the breaks on their relationship. 

"Scott and Sofia are spending time apart," a source confirmed to Us Weekly. "She is making it a point to do her own thing."

Disick is also doing his own thing, with the Keeping Up With the Kardashians star spotted holidaying at Idaho's Lake Coeur d'Alene with ex Kourtney Kardashian and their three children, Mason, 10, Penelope, eight, and Reign, five. 

For now, Disick is choosing to focus on spending quality time with his kids, which E! News suggests is tough for Richie as it means he will also spend more time with Kardashian, who he dated from 2006 to 2015. 

"Things haven't been great between them," a source said of Disick and Richie's relationship. "Scott's been spending every day with Kourtney and the kids and has been vacationing with her. Things are always tense between Scott and Sofia when he goes away without her."

It doesn't help matters that Disick has been leaving flirty comments on Kardashian's bikini photos on Instagram.

Most recently, the 41-year-old shared a selfie of herself in a metallic bikini, with the caption, "lake ya." Disick's response? "What a lake er."

Then back in June, one month after he split from Richie for the first time, Disick praised his baby mama's outfit when he wrote, "Cute shirt."

It's no wonder Disick and Richie are drifting apart, with the source noting they "aren't taking their relationship as seriously this time around". 

Only time will tell if the third time's the charm for the pair...
