It doesn't seem like Kourtney Kardashian is dealing well with the possibility of Scott Disick proposing to Sofia Richie. It is being reported that after Scott Disick was spotted browsing at engagement rings, ex Kourtney Kardashian is terrified he's going to propose to 20-year-old GF Sofia Richie.

Apparently, now that Kourtney Kardashian has finally accepted ex Scott Disick and GF Sofia Richie's relationship, he appears ready to take things to the next level with the 20-year-old heiress. The 35-year-old browsed through the engagement ring selection at Polacheck's luxe jewellery store in Calabasas and Kourt is apparently terrified he's going to pop the question to Sofia. "Kourtney is freaked out about the idea of Scott proposing to Sofia. The closer Kourtney, Sofia and Scott have all become over the holidays, the more Kourtney realizes how in love Scott is with Sofia and that a proposal could be right around the corner," a source close to Kourt tells HollywoodLife.com exclusively.

It is known that Kourtney Kardashian and Scott Disick were together for nine years but never married.

"While Kourtney is happy to see Scott so grounded, stable and in a healthy relationship, it also scares her to think that she could lose him forever. In the back of her heart, she always thought about maybe having more kids with Scott or that one day they might get back together," the source continued.

Reportedly Kourtney has talked in the past about wanting a fourth child to her brood with Scott.

"However, Kourtney knows how unpredictable and romantic Scott can be, so Kourtney is bracing for the shocking surprise that Scott gets engaged to Sofia or worse, suddenly elopes with her which would traumatize Kourtney," the source added.

Reportedly Scott and Sofia dated for well over a year before Kourtney finally gave the couple her blessing.
