Ariana Grande just released “No Tears Left to Cry,” but she’s already teasing her next dreamy song. Taking to social media, the pop princess dropped some sleep-related hints.

She typed the word “r.e.m.” upside down, leading some fans to believe that is the title of the song. However, she took to Instagram Stories to clarify her post by sharing the definition for “REM,” a type of sleep that “occurs at intervals during the night and is characterized by rapid eye movements.”

Then, Ari seemed to type out song lyrics on Twitter. “you’re such a dream to me,” she wrote. “last night ….. boy i met you … yea ….. when i was sleeeeeeep … you’re such a dream to me. and it was on a day like this … yeah … if you can belieeeeve … if you can believe … you’re such a dream to me.”

Grande did not reveal when the song will drop, but said it is “not quite yet” ready for release. She is, however, set to take over “The Tonight Show” on May 1.

Ariana’s new singles will appear on her highly-anticipated fourth album, her first since 2016’s Dangerous Woman.
