Olivia and John share a two-year-old son, Malcolm, and he was also at the wedding. They first announced they were expecting their little boy in September 2021.

It's the second marriage for John, though, the first marriage for Olivia, who previously dated NFL star quarterback Aaron Rodgers.

PEOPLE was the first to report Olivia and John's marriage.

INVESTIGATING THE INEXPLICABLE

The wedding comes on the heels of Olivia announcing in March she was battling breast cancer. She was diagnosed in 2023 and underwent multiple surgical procedures, including a double mastectomy.

Olivia also revealed in May she had her uterus and other reproductive organs removed in her fight against cancer ... freezing her eggs so she could have more kids with John in the future, if they so decide.
