ET's Lauren Zima sat down with the 31-year-old country singer for a Facebook Live interview
on Tuesday, where he addressed the romance rumors surrounding him and Osbourne, thanks to the pair's social media antics. Osbourne recently posted a video of the two blowing out a candle on a slice of cheesecake, calling him her "boo" and writing that the two were celebrating their first anniversary.
Lynch also posted a snap of their cute outing.
"We are pretty odd together aren't we?" Lynch said, referring to Osbourne's hashtag reading "#TheOddCouple." "I think she kind of hit the nail in the head, the odd couple. I mean, I'm from Tennessee -- a small town -- and she's the daughter of the Prince of Darkness."
Lynch shared that he and Osbourne met at the Stagecoach Country Music Festival last year, but said that the two are not dating -- rather, the two were celebrating their "friendaversary." He did, however, gush about the outspoken 32-year-old star.
"She has one of the best personalities and sense of humors of all time, and makes me laugh like crazy," he said. "I think I make her laugh because I'm so backwards of what she's used to out here. We love laughing together, having a good time picking on each other, giving each other a hard time."
Lynch said that he's currently single, but hardly has time for a social life these days.
"[But I'm] always mingling," he joked when asked if he was "single and ready to mingle."
