Frankie Grande barely waited until after his sister Ariana’s wedding to start planning his own.

The dancer, 38, proposed to boyfriend Hale Leon earlier this week with matching diamond-covered David Yurman bands at Dreamscape in Los Angeles, where the couple went on one of their first dates.

The rings feature 2.76 carats of diamonds arranged in a cable pattern, and retail for $10,250 each.

Grande got down on one knee at the end of a virtual reality adventure that included fireworks and a “Will you marry me?” banner.

The Broadway star revealed he had been planning the proposal for more than a year, but was delayed by the coronavirus pandemic.

He met Leon, 28, in 2019 at a line dancing bar, calling it “love at first dance.”

Ariana, 27, was present for the proposal and might have some advice for her brother now that she’s a married woman; the pop star wed Dalton Gomez in May at her Montecito, Calif. home, wearing an Audrey Hepburn-inspired Vera Wang dress.

The pop star’s own wedding stack was designed by Gomez, 25, who incorporated a pearl from her grandmother into a unique engagement ring design.
