In the pictures, Greer and her boyfriend -- whom she chose not to identify by name -- were embracing, kissing, enjoying dinners out, boating, and ice skating. They also apparently spent Christmas together.
Congratulatory and supportive comments rolled in from Bachelor Nation.
The Bachelor 27 runner-up Gabi Elnicki commented, "Finally!!!! We love to see it," suggesting that Greer has been dating her boyfriend for a while now.
But the pair's connection slowly fizzled out as Greer patiently waited for a one-on-one date, and then she and Zach memorably had a heated exchange via virtual chat when he was sick with coronavirus.

Greer then missed out on a significant amount of time with Zach when she came down with COVID-19 herself and was forced to quarantine in her hotel room while traveling internationally on Zach's season. Once Greer felt better, she reunited with Zach and his remaining bachelorettes in Budapest, Hungary.
Zach, however, chose to eliminate the medical sales representative from Houston, TX, in Budapest because he just didn't think their relationship could catch up to what he had built with several other women.
"Time is really of the essence, and we didn't have much of it," Greer told Zach during their breakup.
"We were robbed of it, and I just have to accept that. I really appreciate you being so honest and transparent with me, so thank you."
And Greer lamented in her final words on the show, "I think the hardest part is... we had so much time that was robbed. I think maybe we could've gotten there, if we had the time, but I can't think that way because it's not what happened. It's out of my control."
"I'm just tired of putting myself out there and getting nothing in return," she added.
Greer and Brooklyn both went on to look for love on Bachelor in Paradise last year. Both women, however, failed to make a strong or lasting connection, and so they were both denied roses during the same early October episode.
Greer cried following her ouster about how her heart felt "tired" while searching for The One.
"My heart feels tired. I'm coming to terms with this reality that I'm not going to find love in Paradise. It hurts to put yourself out there and not be reciprocated," Greer said.
"I wanted it to work so badly because I have so much love to give. I'm just ready to have someone be able to love me as much as I love them. I want that happy ending, and that's the harsh reality -- is I just want to be chosen."
