Bella also shared a number of other shots from Jessica's big day, including one of the bride clutching a stunning bouquet of fuchsia coloured flowers.
Jessica is the younger sister of Home and Away's Penny McNamee, who appeared to be notably absent from Jess' big day.
She and Australian-born husband Patrick are based in the US, and prefer to live a private life away from the spotlight of the entertainment industry.
Jessica previously told the Herald Sun she wished to keep their engagement "under wraps", saying: "He's a lovely Australian boy who has moved to America.
"He's not in the business which is great. He's a property developer."
