Jenna Dewan Shares Video of Ex Channing Tatum Cheering on Daughter at Dance Competition
View Story"I've just entered the second trimester, and I feel alive again," she told the publication at the time, before she shared how she's not sure whether her body will react to the growing baby and postpartum experience the same way it did her previous pregnancies.
"I'm not sure the body necessarily gets right back into action the way it did years ago. We'll see. I'll report back, but I do think there's a bit of ignorance, this dancer in me that just says 'OK, well, you just get it done,'" she said. "I've recovered great every time, but I'm open to whatever happens."
She told the outlet she and her partner did not find out the baby's sex ahead of time, explaining that they're not racing "to the end" with this pregnancy "because this is the last time." She added: "There's a bit of joy and a little sadness. I'm really trying to enjoy it all and not try to just get through the day."
