Fans of Selling Sunset will know that while the fourth season dropped on Netflix recently, there was one thing missing - Chrishell and Jason Oppenheim's romance.
The pair went official in July but so far have kept their romance off the programme. Viewers are desperate to know why, and in a recent interview, Jason revealed the real reason the pair kept their blossoming relationship under wraps.
Speaking in an interview with US Weekly, Jason said it was Chrishell's decision to stay private. He shared: "I think when [a relationship is] public, it puts a lot of added pressures and publicity and opinion.
"I think it’s nice to kind of start a relationship in the way that normal relationships kind of grow and progress. And that’s just between two people.
"We told some close friends, but if you want to keep something private, you have to generally not tell too many people. It’s hard to keep a secret amongst a lot of people."
