It's unknown how long the pair have been seeing each other, but Hannah revealed in a YouTube video in November that she had signed up for a dating app and was ready for romance for the first time in over a year.
Her season finale of The Bachelorette in 2019 saw her failed engagement to Jed Wyatt, and while she tried to give it another shot with her runner-up, Tyler Cameron, things quickly fizzled out.
Current Bachelor star Matt James -- who has long been friends with Cameron and Brown -- recently opened up to ET about her new rumored romance and said he was fully supportive.
"I couldn't approve more," James shared. "I actually had a chance to meet him, and he's incredible."
"He's a really good guy, and I'm excited for Hannah and Tyler [Cameron] because I think people can see they can co-exist. They can be happy with people that aren't Tyler and Hannah," he added.
