Ever the doting dad, the Passengers star carried his daughter, who wore a pink shirt and leggings combo, for much of the walk through the city. 

Katherine – who is showing a big baby bump but has yet to confirm she is pregnant – wore a black shirt that clung to her tummy and leggings. 

She walked in clean white shoes and donned a visor to keep the sun off her perfectly tanned skin.
