Poor Sofia! On Sept. 29, Scott Disick and his baby mama, Kourtney Kardashian, reunited for a family vacation in NYC with their three children — Mason, 8, Penelope, 6, and Reign, 3. Despite the fact that the trip was hardly romantic, Scott’s girlfriend, Sofia Richie, is reportedly freaking out.

“Sofia is trying her hardest to be super cool about it all, and pretend like it doesn’t faze her that Scott and Kourtney took the kids to New York together, but of course it does,” a source told Hollywood Life. “Sofia is really struggling when it comes to how close Scott is to Kourtney,” they added. “It’s a never-ending source of angst for her. Sofia is convinced that Scott is still totally in love with Kourtney, and that if Kourtney would take him back Sofia believes he would drop her in a heartbeat.”

Unfortunately for the 20-year-old model, this isn’t the first time she’s been forced to worry about her man and his ex. “Sofia is furious that Scott and Kourtney are hanging out again,” an insider revealed to Life & Style shortly after Scott and Kourt were spotted getting cozy at Kylie Jenner’s 21st birthday bash. “Sofia understands that they have to remain civil for the kids but has become convinced that Kourtney is trying to steal back her man,” they added.

Question is, why doesn’t Sofia just talk to Scott about her concerns? After all, they’re the ones in a relationship! Well, according to Hollywood Life once again, “Sofia knows there’s really nothing she can do about it though. She just has to grin and bear it, because if she tries to put her foot down she will very likely lose Scott forever, and that’s the last thing she wants.”

Hmmm, well, here’s hoping that Sofia’s suspicions are just that — suspicions! After all, Kourt’s been spotted out with her alleged new boo, Luka Sabbat, so we seriously doubt she’s planning to start something up with Scott again. Then again, who knows if things are ever really over with those two?!
