Though there are no photos of Scott and Kourtney together, both parties have uploaded pictures of themselves and the kids to their respective social media accounts.
Scott hinted at a break up when he posted a photo of himself sitting by the pool at the luxury Utah retreat captioned: "Little water never hurt nobody."
His post was met with many comments encouraging him to rekindle his romance with Kourtney.
"Skourt!!!!!!!!!" one fan wrote whilst another commented, "Go get our lady, Lord #Skourtney 4 eva."
Kourtney, meanwhile, kept birthday boy Scott out of the pictures but shared snaps of herself and their three children Mason, 10, Penelope, seven, and Reign, five, horseriding.
"Escape to the desert," she captioned a bikini snap of herself in the desert.
Later on, Kourtney shared a photo of herself and sister Kylie Jenner, who then shared her own photo with Scott from the same occasion.
According to Page Six, Kourtney never saw eye-to-eye with Sofia.
"Scott had gone back to his old ways and Sofia got fed up," the source said adding, "Kourtney didn’t make it easy for her and you can only tolerate that kind of treatment for so long."
Kourtney has stated that she and Scott are "soulmates in a sense."
Though Scott said he didn’t want to disrespect his relationship with Sofia on an episode of Keeping Up With The Kardashians, he did confess: "Whether Kourtney and I are soulmates or not, I feel like I owe a lot to Kourtney for the times that I missed when I wasn’t the best partner to her.
"So I feel like I will forever be making up for that lost time for the rest of her life."
Scott and Sofia started dating in 2017 after they were spotted in Cannes together. Sofia's last post with Scott was taken shortly after Halloween whilst Sofia hasn't appeared on Scott's Instagram since early October.
