Mulroney was with the couple on every step of their wedding journey, from helping to select Bobbie's dream wedding gown to helping Alonzo customize his suit.
Their dream, beach-side wedding took place earlier this year at the Royalton Punta Cana Resort and Casino in the Dominican Republic.
Here are all the details of how Mulroney pulled off the epic wedding.

Mulroney chose an outdoor, waterfront beach gazebo location for the beach-loving couple to say their vows.
The bride loves purple so Mulroney worked in pastel purple roses in the floral arrangements, including the bride's bouquet and the groom's boutonniere. Lilac rose petals decorated the aisle.
Mulroney also incorporated the couple's Bohemian style with touches like loosely-draped fabric on the beach gazebo, wooden cross back chairs with cream cushions and gold geometric lanterns.
The touches continued into the reception, held on the beach under a canopy draped with organza, string lights and hanging terrariums with candles.
A wood table for guests was decorated with a green runner featuring succulents, candles and flowers in the shades of ivory, lilac and blush. Each place setting featured a custom menu in a purple watercolor motif.
The couple's wedding cake was decorated with a lilac hued Chantilly icing that their son chose during their tasting.
