The celebration for Biviano and the former NRL player's only daughter took place over the weekend and included a life-size unicorn, pastel dessert carts, lavish flower styling and a three tier birthday cake.
"Another year has passed & we are happy to see you grow even more beautiful & wiser each year. Our baby, our little girl, our sky blue tressure [sic], we adore you!!!" Biviano wrote.
"No matter how old you are you will always be our baby girl! Our wish for you is to love life & never stop dreaming... May you always be surrounded with love, health, happiness & magic!"
