Plus, the dancer talks about how her new boyfriend, Steve Kazee, has turned her into a major WWE fan!
Jenna Dewan is getting candid about the ups and downs of life in the spotlight.
The 38-year-old dancer was a guest on The Ellen DeGeneres Show on Friday, where she opened up to guest host John Cena about her "very intense" year.
Dewan, who announced last April that she and Channing Tatum were separating, was on the show to promote her new book, Gracefully You: How to Live Your Best Life Every Day, out Oct. 22. She told Cena that the book will explore her journey to finding happiness again and being open to change.
"It's kind of a combination of a lot of things," she explained. "It's no secret that I had a very intense year and a lot of change."
"I'm a hippie at heart," she added. "I'm sort of a seeker. I like to do practices and rituals and things that sort of connect me to something greater than myself, bigger than myself. Through that, I used a lot of those techniques to help me through change. There's a lot of personal stories; there's a lot that I go into. ... It was really cathartic and fun to write this."
Earlier in the show, Dewan also revealed that her new boyfriend, Steve Kazee, has turned her into a major WWE fan.
"I know all about you," she told Cena. "Steve, my boyfriend, is a huge wrestling fan and he got me, like, so into it. So much that I watched WrestleMania by myself."
"He wasn't even in town and I watched WrestleMania  because I had to know if Becky Lynch was going to beat Ronda Rousey," she continued, referencing the match that made history earlier this month for having women be the main event for the first time ever. "I was by myself, I ordered it ... I was sitting there, like texting, 'Do you know what's happening?' I had to! I had to know. I was hooked!"
