After years of romance rumors, singer Hayley Kiyoko and Bachelor Nation's Becca Tilley finally confirmed their relationship in 2022.

The couple made their official debut at the release party for Kiyoko's song "For The Girls," the music video for which features a cameo by Tilley. During the event, Kiyoko pulled the reality star onstage, where they shared a hug and a kiss.

The singer's Instagram revealed that she and Tilley had been dating for four years and first met in 2018. "This photo is from the first night we met at my Expectations album release party, we took this picture after 5 minutes," Kiyoko captioned a photo of the couple smiling with Tilley's arm around her waist. "Her shirt said 'no time for romance'…..it's been 4 years. I guess she had some time 🤷‍♀️"

Though Tilley told PEOPLE she was off the market in 2018, she was hesitant to share her life with Kiyoko given her past public romances; particularly her year-long relationship with Bachelor Nation's Robert Graham.

However, the couple felt it was time to unveil their love to the world in 2022 — and they haven't looked back.

"It feels really good," Kiyoko told PEOPLE shortly after going public with Tilley. "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."
