The pair confirmed the news via Instagram on Aug. 30 when Hampshire posted a sweet photo of them together. “Just me & my girlfriend. 🎶❤️👯♀️🍓” Hampshire, 37, captioned the shot.
In the image, Geiger and the actress, best known for playing Stevie Buddgo on the Canadian sitcom, opt for a similar look by both sporting glasses.
Just a few days later, Geiger raved about Hampshire on Instagram.
“I love her so much and miss her so much,” the 29-year-old musician wrote alongside a close-up shot of Hampshire in her black-rim glasses. “And I need to kiss her and I want to go dancing because she is so cute when she dances and she is my dream and and and goodnight 😘”
Two weeks ago, Hampshire shared another post where the pair got silly in a photo booth, captioning the images “Photo booth-a #tuscany”
On Aug. 30, Geiger snapped another image and lovingly captioned it: “I am so happy this woman is alive… with the sound of music. She is a song I will sing for a thousand years. She fills my heart with the sound of music. My heart wants to sing every song it hears.”
The lyrical caption makes reference to the 1965 film The Sound of Music.
This is Geiger’s first public relationship since transitioning. The musician — who has written hits for Shawn Mendes and One Direction — was first discovered on VH1’s 2004 reality competition In Search of the Partridge Family.
Geiger later went on to tour with Hilary Duff and release the 2006 album Underage Thinking, which included the Top 40 single “For You I Will (Confidence).”
In Oct. 2017, the singer came out as transgender, revealing she had begun transitioning earlier that fall. After a fan inquired about why Geiger looked different recently, the singer-songwriter responded, “Okay… because u asked nicely… I am transitioning.”
Added Geiger: “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. So here goes. Love it or hate this is who i have been for a looooong time. I love u guys. Talk sooooon byeeee.”
