Though a source confirmed to PEOPLE that the couple had not broken up, it seems as if the pressures of being in front of the camera yet again are putting a stress on the relationship. “Rob just got super emotional and felt too overwhelmed,” a source close to the Kardashian-Jenner clan tells PEOPLE of the brief tiff. “He lashed out from being frustrated, and they broke things off while they were filming. They got back together hours later.” The insider adds, “Getting back in front of the cameras has been hard on Rob as he hasn’t been doing anything for a really long time now. Being in the limelight all of a sudden again is a big deal for him. He’s working on himself and getting re-adjusted and taking things one step at a time, but things are definitely on the upswing for them.” While the engaged couple continue to film for their new reality show, Rob & Chyna, the preparation for the has trumped everything else. “They are both very excited about the baby,” a source previously told PEOPLE, so “it’s hard to see Rob and Chyna actually splitting. Rob is looking forward to becoming a dad. It would take a lot for him to break up with her.” Though the 29-year-old Keeping Up with the Kardashians star and his fiancée did not attend ‘s birthday celebration on Sunday evening, a source confirmed that the invitation was indeed extended to each of them. “Again, Rob and Chyna are taking things one step at a time,” the source says. “They’re trying to be healthy, eat well, treat each other well and treat their minds and bodies well.” Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E! and Rob & Chyna premieres later this year.
