"It might be a fine line, but I don't want anyone to think I was ashamed or embarrassed," she told the outlet. "That was really important to me."
Tilley had previously talked about her relationship with Kiyoko on her podcast Scrubbing In with Becca Tilley & Tanya Rad though the references fell under the radar as she used a nickname for the singer, "95p," The Cut explained. The nickname referred to Tilley's feeling that she was 95 percent sure the two would get married.
Tilley explained that in her day-to-day life when she would be around friends and family or bump into fans, she would introduce Kiyoko, 31, as her girlfriend.
"When we're walking around, we're holding hands," Tilley said. "If I meet someone who's a podcast listener, I'm like, 'This is my girlfriend, Hayley.' It's never been, 'This is my friend.'"
Even then, she said, some people just didn't get it. When she would visit the pop star on tour, some would assume the two were good friends.
"I'd go visit her on tour, and I posted about it on Instagram. People just thought I was great friends with Hayley. Huge fan," Tilley joked.

Tilley was featured in the music video for Kiyoko's single "For the Girls," which premiered in May. While speaking to the crowd at Mickey's in West Hollywood to celebrate the single, Kiyoko pulled Tilley onstage.
"Where's Becca?" said Kiyoko as she looked for Tilley.
After Tilley made her way onstage, Kiyoko handed her a "final rose" before they shared a hug and sweet kiss.
The couple was also spotted showing off PDA throughout the night as they danced with pals and made the rounds.
A few days later, Tilley shared her version of their relationship launch on Instagram by posting a video montage of her romance with Kiyoko. "hard to say if this is a hard or soft launch, but it is a launch ❤️ #95p."
In June, Tilley opened up about the outpouring of love she's received from fans at iHeartRadio KIIS FM's Wango Tango.
"It feels really good," she told PEOPLE of unveiling her relationship. "I mean, we lived a very normal life. It just wasn't on social media. We lived very open. And we've been together for four years, but now it's on social media. And now we get to share with the world. It's just been really nice — we've had so much love and support."
