This marks Geiger's first public relationship since transitioning. The singer-songwriter, who has written hits for artists like Shawn Mendes and One Direction -- came out as transgender last October.
The Buffalo, New York, native announced the news via Instagram at the time, replying to a fan who asked, "Tell us, why do you look different lately?"
"Okay… because u asked nicely… I am transitioning," Geiger explained at the time. "I started talking about it with a couple of my close friends and family about a month ago and it’s given me the courage to start the process."
"I feel like the next step is to tell all y’all," she continued. "So here goes. Love it or hate this is who I have been for a looooong time. I love u guys. Talk sooooon byeeee."
