Alongside a Boomerang clip of the spouses with two balloons, Henrie wrote Wednesday, “After getting married my life started to take on a meaning and importance that’s indescribable … [one] I’d never felt before and made my such a better person … “
He continued, “I can not wait to see what being a poppa brings. I can not wait!!!”
Following his Old Hollywood-inspired wedding, held in Southern California, the actor told PEOPLE exclusively, “You always hear you should marry your best friend, and I actually get to do it. You don’t meet girls like her every day.”
Wearing an A-line, full-length gown featuring beaded Alencon and Chantilly lace by Enzoani, Cahill exchanged traditional vows with Henrie, who wore a custom tuxedo by Indochino and a white bowtie (“My dad got married in a white bowtie, so I’m honoring him,” the star said).
Cahill told PEOPLE of her new husband, “One of my favorite things about him is how funny he is and how we just get each other. Being married is going to be just that much better.”
