He proposed at the site of one of the couple's memorable first dates: Dreamscape, an immersive VR adventure venue in Los Angeles. The Rainbowthon host worked with the company to create a custom ending to the couple's VR experience, complete with a "Will you marry me?" message and intergalactic virtual fireworks.

"It was such a perfect, beautiful moment," Frankie told PEOPLE of the big moment. "Hale was completely surprised and we both started crying tears of joy. I have been working on proposing to him in virtual reality for over a year and it was ABSOLUTELY breathtaking for us both."

In attendance were the couple's closest family and friends, including Frankie's mother Joan and Hale's aunt Carolyn.

The couple met in 2019 at a line dancing bar in Los Angeles, which Frankie playfully called "love at first dance."

"I randomly ended up going to this bar Oil Can Harry's in the Valley and I saw Hale he was dancing on the stage," the host told PEOPLE shortly after they started dating. "He was performing for everybody. He loves to go to Oil Can Harry's! He knew all the dances; I was blown away."

Love is in the air for the Grande family, as Frankie's younger sister tied the knot with Dalton Gomez just weeks ago in May.

"They got married," Ariana's rep told PEOPLE at the time. "It was tiny and intimate - less than 20 people. The room was so happy and full of love. The couple and both families couldn't be happier."
