Discussing her split with Tatum, 38, Jenna revealed that it's been a period of adjustment for the close-knit trio.
"We’re just getting used to it. We're in a very positive energy together, trying to be the best parents to Everly. We support each other," the 37-year-old told Harper's Bazaar.
"I feel a sense of joy and freedom and excitement, truly, about a new chapter in my life," Jenna continued.
The couple, who met on the set of Step Up in 2006, shared identical messages on their social media accounts. Despite the break-up Jenna and Channing still maintain they love each other, "we fell deeply in love so many years ago and have had a magical journey together. Absolutely nothing has changed about how much we love one another, but love is a beautiful adventure that is taking us on different paths for now."
