Are they on or are they off? According to reports, Sofia Richie and Scott Disick are officially off – and Scott intends to keep it that way!

After briefly giving things another try last month (they first broke up in May after three years together), Scott Disick and Sofia Richie have officially called things off for good. And it doesn’t seem like an amicable break-up either, as the pair reportedly aren’t even on speaking terms…

“They have been off and on for two months,” a source told E! News.

“Sofia really pushed to make things work between them after they initially broke up, but Scott officially called it off recently and they are no longer speaking.”

According to the source, quite a few things contributed to the permanent break-up…

Age reportedly played a huge part (Scott is 37, whereas Sofia is just 21 years old!) as did the fact that Scott wanted a more quiet lifestyle, and wanted to focus on his children and businesses. (He has three children with ex Kourtney Kardashian – Mason, 10, Penelope, 8, and Reign, 5.)

“Friends attributed their 15-year age difference becoming an issue,” the source continued.

“He’s in a very much different place in his life, really focused on a more quiet lifestyle, his kids and his investment businesses.

“And Sofia, at 21 years, really still trying to figure what she wants to do which drove them apart over time.

“Scott was very clear with his decision to end things and doesn’t see them getting back together again in the future.”

As much as we were rooting for them, we won’t lie and say we didn’t see this coming. Especially as we previously heard that Scott and Sofia weren’t getting on after briefly reconciling – partly due to him spending all of his free time with Kourtney and the children.

“Things haven’t been great between them,” an insider shared with E! News at the time.

“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.”

We’re very interested to see who Scott and Sofia will date next…

Any ideas?
