30-year-old Smith wore a navy suit and tie with a white shirt while his 26-year-old sweetheart appeared wearing a white silk dress.
The couple swept promises at a cherished ceremony at St Bernard Catholic Church in Claremont.
Afterwards, the couple were freshened up with rose petals and fluffed up away in the Bentley to join family and friends at a reception overlooking the Atlantic Ocean.
