In her Wednesday announcement, Gaga revealed that her song for the film, titled "Hold My Hand," would premiere this Tuesday — and called it a "love letter" to her fans.

"When I wrote this song for Top Gun: Maverick, I didn't even realize the multiple layers it spanned across the film's heart, my own psyche, and the nature of the world we've been living in. I've been working on it for years, perfecting it, trying to make it ours," she wrote on Instagram announcing the news. "I wanted to make music into a song where we share our deep need to both be understood and try to understand each other — a longing to be close when we feel so far away and an ability to celebrate life's heroes."

Gaga continued, "I'm so grateful to Tom and Hans and Joe for this opportunity — and it's been a beautiful experience working with them. Me, BloodPop, Ben Rice and everyone else who worked on it with us are so excited to share it with you. This song is a love letter to the world during and after a very hard time. I've wanted you to hear it for so long. And I'm so excited to give it to you on May 3. 'Hold My Hand.' "

Two days earlier, Gaga teased the single by tweeting a few lyrics from it: "Hold my hand everything will be ok I heard from the heavens that clouds have been grey."

Top Gun: Maverick sees the return of Cruise for his role as Pete "Maverick" Mitchell, a pilot student training with the U.S. Navy in the 1986 original. The movie will hit theaters May 27.

"We worked with the Navy and the Top Gun school to formulate how to shoot it practically. Because if we're gonna do it, we're gonna fly in the F-18s," said Cruise in a behind-the-scenes featurette released last month. Producer Jerry Bruckheimer added, "The aviation sequences had to be real, so our actors went through three months of grueling training."

Footage showed Miles Teller, Glen Powell, Monica Barbaro, Greg Tarzan Davis, Jay Ellis and more stars doing training exercises and flying in the high-speed planes. Cruise said they did a "challenging" underwater program that simulates how to get out of an aircraft if they landed in water.

"Tom designed this all-encompassing aviation training for all the actors," said Barbaro.
