Fox shared video of Kelly taking a knee at the top of a flight of outdoor stairs under the tree where the two say they fell in love in July of 2020.
“Somehow a year and a half later, having walked through hell together, and having laughed more than I ever imagined possible, he asked me to marry him,” Fox wrote in the post. “And just as in every lifetime before this one, and in every lifetime that will follow it, I said yes.”
An Instagram video from Kelly shows Fox wearing the two merged rings he had made for the occasion, with a diamond and an emerald that form “the obscure heart that is our love.”
Fox ended her post with, “and then we drank each other’s blood,” a moment not shown in the video.
It’s the second marriage for Fox, the 35-year-old star of the “Transformers” films. She was married to actor Brian Austin Green from 2010 to 2021. The two have three sons together.
It’s the first marriage for the 31-year-old Kelly, who has a daughter from a previous relationship.
