The beautiful actress wowed at a photocall for her new movie Guardians of the Galaxy in the sunny capital on Friday morning (25 July).
Zoe looked drop dead gorgeous in a cream frock, that gave a hint of blossoming baby bump – although the 36-year-old has yet to confirm the widespread pregnancy speculation.
She married Italian artist Marco Perego at small ceremony last year, but they have kept details of their big day private.
Guardians of the Galaxy is a brand new superhero film based on the Marvel Comics superhero team. Its all-star cast includes Bradley Cooper, Benicio del Toro, Chris Pratt, Vin Diesel and Doctor Who actress Karen Gillan.
