John was also a contestant on Katie’s season of “The Bachelor” and Us Weekly confirmed their relationship earlier this month.
The news came after Katie dedicated Taylor Swift’s 2012 song “Begin Again” to Hersey as part of her “12 Days of Messy” challenge.
In “Begin Again,” Taylor sings about falling in love again after a failed relationship.
On the same day, Katie also posted a clip of John's limo entrance from "The Bachelorette." In the clip, she said as John was walking away, "Yeah, that’s my type. I think that’s my type. Did he hear me? Play it cool."
Katie's rep confirmed the "romantic connection," telling Page Six, "It’s known Katie and John became close friends post-season. John has been there for her through all the major changes in her life, and they are excited to explore this newly found romantic connection.”
In another recent Instagram from this month, which featured individual Polaroids of John and Katie, she quipped, “Y’all getting wild in my DMs.”
