Jenna Dewan has opened up about the breakdown of her marriage to actor Channing Tatum, claiming he "wasn't available" for weeks after she gave birth to their daughter.

The actress/dancer, 40, met the Hollywood hunk on the set of their 2006 film Step Up with their onscreen chemistry translating into a real-life romance.

They married in 2009 and welcomed daughter Everly in 2013, before announcing their shock split in April 2018.

After giving birth to Everly, now eight, Jenna said she continued to work and travel with the then-newborn. She added that her then-husband, however, "wasn't available" for some time due to his work schedule.

"I had to travel with her and at the time, Chan wasn't available to be with us for the most part. So, it was me, my doula, and Evie all by ourselves traveling at six weeks," she said, appearing on the Dear Gabby podcast.

The star explained how balancing motherhood and her work was "really hard," especially as she was on set for "long hours."

"I did have her on set with me constantly. It was just really difficult," she added. Jenna also revealed that she had "a lot of postpartum anxiety" at the time.

"It was like, I just never stopped. You know, you're up a couple times in the night and then you're working all day," she recalled. "I was breastfeeding, I was pumping, I was without a partner, I mean it was just craziness."

Jenna and Channing decided to split the night before she started filming the second series of her TV show World of Dance in January 2018.

Since splitting from Channing, Jenna has gone on to find love with fiancé Steve Kazee.

The pair welcomed their son Callum last year, making Jenna a proud mother of two.

Jenna confirmed her relationship with the Grammy Award winner in October 2018 and announced their engagement in February.

As for her experience with her second child, Jenna remembered the time as being "so grounded."

"Even though the world was crazy, I was home and in this love nest and it was different," she said of raising baby Callum with her new man amid the pandemic.
