The Sin City actress was spotted making her way through the departure lounge at LAX, looking both cosy and stylish before boarding her long-haul flight.
Jess oozed effortless cool in a navy and white striped top which appeared to be emblazoned with the words 'Je t'aime' in red sequins. Cute!
To up the comfort factor, the yummy mummy wore a pair of loose black trousers and practical flat shoes.
She also sported a long navy coat which fell below her knees, rocking tousled bedhead locks and a cherry red Saint Laurent bag.
Jess opted for fuss-free make-up, showcasing her stunning natural beauty with just a few lashings of mascara and clear lipgloss.
And in true celeb style she snapped a mid-flight selfie, posing with a pal after changing into their matching white pyjamas!
Jess added the caption: "Off to #Paris w my bebé @kellysawyer #matching #jammies #AirFrance!"
See, she even makes boring white PJs look good. Hmph. Not fair!
