Why Did Channing Tatum Leave Jenna Dewan? Jenna Spills the Tea in Her Book

Very shortly after Channing and Jenna split, he made his relationship with Jessie J public. 

And Jenna found out about it just like the rest of us: over the internet. “I was learning things about my ex most people wouldn’t have to face — and over the internet, as it was happening,” she wrote. “There I was, on a plane, alone, finding out about his new relationship. I felt blindsided. Choosing grace as I learned everything about my personal situation along with the rest of the world was really difficult.”
