Blake reposted the photo and captioned it, "Look at us babies," along with laughing and heart-eyes emoticons, Us reported.
Becca also jokingly gave Blake a rose during a night out with friends, an event which was reportedly documented on Kendall Long's Instagram Stories earlier this month.
Blake confirmed he and Becca have "a great relationship" during a March appearance on Us' "Here for the Right Reasons" podcast.
"We talk, we're friends," Blake said at the time. "And also, the way her and Garrett ended, I think people just want to see me and Becca happy, which is a compliment, like, it means a lot. It really, really does."
Blake continued, "We're close friends and everything and we're, like, always gonna have each other's back and care for each other. But I don't know why everybody was shipping us or still is shipping us so hard."
Dating gossip centered around Becca and Blake even dated back to December 2020.
Becca and Blake's breakup on The Bachelorette finale in August 2018 was excruciating to watch considering Blake said he was madly in love with the show's leading lady at the time.
