The majority of photos included Brown, whom Underwood has been privately dating. It wasn't until Brown's own birthday in December that Underwood shared a photo of his boyfriend, and gave a look inside their relationship. "Love," Underwood captioned the Instagram story.

Underwood previously spoke to PEOPLE about keeping his relationship with Brown off-screen, including in his Netflix documentary series Coming Out Colton. "After The Bachelor, I learned the boundaries and healthiness of having a private relationship," he explained. "Everybody went through my breakup [with Cassie Randolph] and the ups and downs of my dating life. It's nice for me to have something for myself."

Underwood dated his Bachelor pick Randolph for over a year before they split in May 2020. That September, she filed a restraining order against him for allegations including stalking and harassment. (The order was dropped two months later.)

Speaking about his relationship with Brown, Underwood previously told PEOPLE, "I'm the luckiest person to have him in my life," and confirmed he's "very much in love."
