"With two kids, we have our hands full, but every day in a new adventure," Jessica recently told US Weekly. "It's fun! I feel very at peace with being a mum."
Initially the singer has planned to keep the sex of her second baby a secret, but memorably let slip that she was having a son on Jimmy Kimmel Live back in March.
She later shared her joy at the prospect of welcoming a little boy into the family. "I'm so excited to have a son," she said at the time of her baby shower in April.
"I didn't grow up with a brother and I think the unknown is really exciting. I can't wait to have that connection with our little man."
Jessica has already showed off her slim post-baby body on a number of occasions – but it was recently revealed that she has re-signed to Weight Watchers.
The blonde beauty reportedly earned $4million in 2012 for her work with the weight loss company following her first pregnancy with daughter Maxwell.
It's a little princess!
