The mother-of-two uploaded a photo to Twitter on Saturday night (14 December) showing herself pulling her fiercest pout for the camera, adding the caption: "Aquaphor from the diaper bag...And a filter ;) Date night!"
Gorgeous Jess, 33, was enjoying a night out with fiance Eric Johnson.
The couple have been engaged since November 2010 and actually planned two weddings, both of which were called off because Jessica fell pregnant. First with daughter Maxwell, born in 2012, then with son Ace, born the following year.
Showing a sense of humour about it, she described Eric in a recent interview with USA Today as her "almost husband."
She added in the chat that she's now regained her pre-pregnancy figure via a Weight Watchers programme (which she is the face of) and that the couple are now planning for the third time.
"I've been pulling all kinds of sketches for dresses and colours. It's a good goal for me. It's good for me to feel the best I've ever felt when I walk down the aisle.
"I'm the luckiest girl in the world to have Eric with me and by my side, and he's an unbelievable dad."
