Zach Wilson and Nicolette Dellanno got engaged in June while on vacation in Italy. At the time, Wilson shared an Instagram post documenting the moment and how lucky he was to have his now-fiancee in his life.

A heart-shaped birthday cake, cinnamon rolls, waffles, fruit, muffins, eggs, donuts and pancakes were all included in the spread. The cake, which featured the number '23' in the middle for Dellanno's age, was decorated with long-stem cherries and delicate buttercream decorations.

Dellano has shared her support for Wilson through the ups and downs of his NFL career. Despite being the backup to quarterback Bo Nix, Dellanno attends every Denver Broncos game wearing the quarterback's jersey to show her support for him whether he takes the field or not.
