The pair attended the premiere of The Hunger Games: Catching Fire in London's Leicester Square yesterday (11 November) and couldn't keep the smiles from their faces, as they kissed and hugged one another in front of fans and their fellow actors.
Sam - who stars in the action packed film series as Finnick Odair - donned a smart navy blue suit for the occasion, which he wore with a white, collarless shirt and burgundy shoes.
Meanwhile, actress Laura stunned in a floor length white gown, which featured intricate detailing around the body and a cut-out back.
The 28-year-old also swept her hair up into a pretty ponytail and opted for natural looking make-up.
At one point on their walk down the red carpet, Sam literally swept his wife off her feet by lifting her up playfully.
And far from being mortified by her hubby's playful nature in public, Laura seemed to love Sam's act of affection and laughed and joked along with him.
But they weren't the only celebs at the premiere who had a fun while posing for snaps, as leading lady Jennifer Lawrence was spotted joking around with co-star Josh Hutcherson outside the cinema.
Even newly formed pop supergroup McBusted got in on the action by stacking themselves into a human pyramid in the middle of the Leicester Square red carpet!
Well, they all certainly know how to make an entrance!
