Meanwhile, more than 20 years after Britney Spears released "Hit Me Baby One More Time," the pop princess reached a major new milestone: Her 1998 hit earned the top spot on Rolling Stone's 100 Greatest Debut Singles of All Time list. And there's plenty more music to celebrate thanks to Lady Gagaand Ariana Grande, who had fans eagerly grabbing for umbrellas after dropping their new song "Rain On Me."

"It was this beautiful, very healing process for me," Gaga said of working with her fellow artist. "Not necessarily having a female artist that mentored me as I came up, and being able to be with her and hold her and be like, 'Anything that you feel chains you, any pop cultural construct that you feel you have to live up to, I'd like you to please forget about it and be yourself.'"

"That woman has been through some really tough, really hard life testing stuff, undoubtedly," she added. "And her ability to move on. When she came into the studio, I was still crying and she was not. And she was like, 'You're going to be okay. Call me, here's my number.'"
