While showing off her baby bump in Stella McCartney for the fashionable Pamela Hanson-shot spread, the "Step Up" beauty opened up about everything from her new body to being married to the "Sexiest Man Alive," Channing Tatum.
"I thought my body was going to change so quickly with pregnancy that I'd freak out. But it was really gradual," the 32-year-old actress/dancer revealed. "There's a reason women are pregnant for nine months; by the end, you're ready to have this baby."
Jenna continued to dish on her personal life and said, "Most actors and actresses are consumed by careers and getting ahead. Channing and I are ambitious, but our relationship comes first."
"We take everything day by day, saying, 'OK, how can we make this work together?'" she added.
Meanwhile, Miss Dewan-Tatum mentioned her and Channing's preferred parenting styles. "Who knows what kind of parents we'll be? We have two dogs, so we've had some practice! And as soon as this baby comes into the world, Channing and I will figure it out real fast."
In regards to how she plans to balance her career and motherly duties, Jenna admitted she's anxious to figure that out. "I think, how in the world am I going to do all this? I have no idea what I'm up against. But I'm as mentally prepared as I can be. It's an adventure!"
