Rodriguez also commemorated the couple's big news on his Instagram Stories, sharing another shot of the two enjoying some post-engagement PDA with a message to the fans.
"There aren't many words to share with you, only feelings," he wrote. "Gratitude. Excitement. And just ... joy."
"We know there is work to do to keep building a family and future we can be proud of, and we can't do it without all of you," the message continued. "We are so thankful for all your messages of love and congratulations."
