The pair enjoyed a day out at Disneyland and stood for an adorable photo outside its iconic Sleeping Beauty's Winter Castle.
Between them stood a member of park staff who'd dressed up as Mickey Mouse, who'd in turn dressed up as Father Christmas, complete with a false beard.
The 40-year-old cut a dashing figure in a pine green jacket that appeared to have been made of suede, as well as a matching pageboy cap.
Beneath the jacket was a collared pearl grey shirt, which he'd left untucked over a pair of pewter grey trousers.
White trainers rounded out the Deadpool star's ensemble, and he'd opted for large-rimmed spectacles as opposed to contact lenses.
Next to him, his wife of four years had put on a flowing pink blouse, rolling its cuffs back over the elbow-length sleeves of her navy blazer.
She complemented her own jacket by way of a pair of faded dark jeans that tightened about her toned legs.
Her voluminous blonde hair cascading freely over her shoulders, the 29-year-old had picked out a pair of black and white Nikes for her day at the theme park.
The previous day, they'd given a joint public debut to their children, two-year-old James and a three-month-old daughter who's name they've yet to reveal.
Reynolds was receiving a star on the Hollywood Walk Of Fame, having given an acclaimed performance this year in Deadpool.
Lively had opted for a sky blue pleated dress, her husband for a sort of three piece suit cobbled together via a midnight blue pea coat, a silver vest and navy slacks.
