“There’s no drama, no ugliness at all. In fact, Ryan and Julianne are talking to each other all the time, even though they have decided to live separately at this time.”
This observation should come as no surprise given that Ryan runs a lucrative entertainment industry empire that includes producing a number of reality shows, including the mega-popular various shows revolving around the Kardashian family. Beyond that though, he also has his American Idol hosting job as well as his daily radio show in LA.
When you pair that with Julianne's burgeoning career as an actress, it simply leaves little room for relationship-building.
