Britney Spears just released her song "Mood Ring," worldwide on Friday.

The song -- which, up until now, was only available in Japan as part of her 2016 album "Glory" -- has been made available on streaming platforms for all fans to enjoy.

The 38-year-old pop singer first announced her plans to release the sultry track, produced by DJ Mustard, in an Instagram Story on Thursday night.

"You’ve been asking for it," she revealed. "Mood ring. Tonight."

The new-ish song comes weeks after fans drove Spears' "Glory" album to the No. 1 spot on the iTunes charts with the #JusticeForGlory campaign and, to celebrate, she revealed a brand-new cover for the album.

Alongside the new album artwork, which features the pop icon in a tiny gold bikini as she arches her back on the ground in a desert, she wrote, "You asked for a new Glory cover and since it went to number one we had to make it happen !!!! Couldn’t have done it without you all."
