Chris, 39, and Katherine, 29, were spotted leaving a gym in Santa Monica.
Katherine was all smiles while keeping it workout chic for the cloudy day out.
Chris appeared quite enthusiastic, as The Lego Movie star gave a thumbs up to the cameras.
That must have been some workout, Chris!
He looked to be similarly excited next to Katherine when they visited an interior design store on Wednesday, February 27.
