The pair shared a video of themselves catching hail in a thunderstorm.
“Soph, it's hailing! Catch one!” Stu yelled from behind the camera, “You're not trying hard enough!”
But fans have taken the opportunity to speculate whether the pair have split.
“Aren't they under contract to appear to be in a relationship still? This video could be old. Or maybe I shouldn't believed everything I read” read one comment.
"Are they still a thing?" read another.
Sophie recently opened up about her relationship with her millionaire beau, saying “I'm just done with it [public opinion]... we can't win.”
“I travel a lot for work. I think they're used to these people coming off the show and being together as a profession everyday, but I'm never home,” she said.
