Naomi looked stunning in a $7,400 white Oscar de la Renta Sweetheart Water Lilly Guipure dress next to her actor husband.
Naomi first sparked rumours that she and Billy had gotten engaged earlier that year, when she debuted an enormous diamond with a tasteful marquise cut, along with a diamond-encrusted band.
The star however refused to confirm the engagement chatter, even after American Today show host Hoda Kotb directly referenced it during a late April appearance on the morning talk show.
