The “God Is a Woman” singer, 25, kissed her fiancé, 24, onstage Saturday at The Sweetener Sessions, an American Express event for her new album at Los Angeles’ Ace Hotel.

Grande wore a Sweetener sweatshirt and tan boots, while Davidson appeared in a black t-shirt and white pants. His tattoos — some of which honor Grande — were on display.

The songstress and Saturday Night Live star have been open about their whirlwind romance, and she recently praised Davidson, for whom she named a track on her album, on Good Morning America.

“It’s just like a feeling, you know?” Grande told Michael Strahan, revealing why she considers the Davidson her soul mate.

Grande laughed and added: “That’s so cheesy. People are always like, ‘When you know you know,’ and you’re like, ‘Yeah, okay, whatever.’ “

Strahan further pressed the pop star, asking for specifics. “You just feel it … He just ticks every box, and it gets better every day,” she responded. “I’m very grateful for him. Life is beautiful.”
