Kourtney Kardashian and Scott Disick's 'awkward' trip with Sofia Richie

Scott Disick was feeling a little pressure on Keeping Up With the Kardashians Sunday, as his model girlfriend of two years, Sofia Richie, made her debut on the show, joining Disick and Kourtney Kardashian's family trip to Finland. Prior to the trip, Disick shared that Richie had vacationed with him and Kardashian before, but mentioned to Disick that she felt "a little left out." "I have to be careful of what I say, because I don't want to overstep anyone's boundary and make anybody feel left out," said Disick. Being that it was Richie's first time traveling with Disick, Kardashian, their children and the reality show's filming crew, Disick was feeling so nervous about everyone feeling comfortable, that he ended up being the one uncomfortable. While at dinner, Richie told Disick, "You're a lot more sophisticated with me when Kourtney's around. You turn into a five-year-old when it's just us." Disick responded, "Well, she's older than me." Later, Disick explained, "Sometimes, you know, you have so many inside jokes or inside things with somebody you've known for so long. Even if you're not romantically with them, you don't really know how to act. I mean, it is definitely a really hard and awkward situation, and I just feel bad because, at the end, I want the people I love in my life to be happy." However, things got even more awkward when they all hopped in the hot tub together. With the whole family in the hot tub, Disick was noticeably uncomfortable as Kardashian began to assist Richie with her makeup. Kardashian told Disick, "You're so negative." "Scott really wanted to come with us to Finland, so I don't know why he's just having such a negative attitude. I want everyone to have a great time and a great experience, and he's just kind of putting a dark cloud over it," said Kardashian. Viewers were divided over Sofia's debut. While some thought the trip was awkward, others took to Twitter to show their respect. Fortunately, after talking to Kardashian and getting some clarity, Disick realized he didn't need to put so much pressure on himself and, in the end, everyone had a great trip together. "At the end of the day, it was honestly just me and maybe some of my insecurities," said Disick. "I think one of the reasons I put so much pressure on myself is that I want these trips to be so perfect. I don't want anything to happen where then people can say, 'This is why I don't like for us all to travel together.' For me, it's one of the best things I have in my life."
