“Mr. and Mrs.,” Ruffalo began. “Incredibly blessed to receive this sacrament together inside the heart of the Catholic Church and holy city.”

She shared a series of photos of the two on their big day.

Lucas responded to the post with his own sweet message to his new wife. “I love you! Easily one of the greatest days of my life. I am so so grateful.

For their special day, Lucas kept it classy with a simple black tuxedo. Ruffalo wore a gorgeous strapless lace dress.

The “Sweet Home Alabama” actor shared additional photos on social media. Ruffalo was seen with a lace umbrella as Lucas was leaning against a wall.

He accompanied the images with a message thanking those who helped make the day happen.

“A huge thank you to deeply talented @caterinaerrani_photography & to @weddings_italy@paolo_nassi @JinaneKafrouny who helped make the dream of wedding in the #vatican come true… many many people to thank for this to come…,” he wrote.

For the last 2 years in Every Way and Every Day this beautiful soul has made me and my life better, deeper, and more whole. I am so grateful and thrilled she said ‘Yes’,” he wrote.

He added, “I WAY love you Brianna. & Thank You to our families and all the people and places that made this come true. I am absolutely aware I got crazy lucky.”

Ruffalo was seen sitting at a table while she wiped happy tears from her eyes. A band played being her as her diamond ring was very prominently on display.

The two started dating in 2022. Ruffalo works as a meteorologist for ABC7 in Los Angeles, according to PEOPLE.

Before Lucas met Ruffalo, he was married to Jessica Clencin Henriquez from 2012 to 2014. The two share a son, Noah, together.

Lucas commented in March 2018 that both he and Henriquez are committed to coparenting their son.
