I found the following article on billboard.com:

Nicki Minaj is teasing a big announcement which just might be a track featuring YG, 2 Chainz and Big Sean. But she can’t seem to make up her mind when it’ll all go down.

With her new album Queen due out next month, the hip-hop star hinted at a star-studded collaboration, and sent her fanbase into a mini-meltdown with the promise of an announcement at 3pm ET Thursday.

And then, abruptly, she put a stop to all that. In response to a seemingly innocuous tweet, Minaj wrote: “Ok well why don’t I just scrap it altogether? No announcement. And another hiatus.” And right on cue, a stream of panicky memes flooded the social network.

And with a final message before bedtime, the announcement is on again. “Tomorrow I’ll feel a lot better & I’ll have more energy to interact with you when I DO go live,” she tweeted.

Over on her Instagram page, Minaj shared a snippet of audio, presumably a chunk of the new track, with a phone-filmed clip of a guy throwing wads of cash in the air like he just don’t care. Minaj tagged YG, 2 Chainz and Big Sean with an emoji-loaded phrase which alludes to the song title. It’s all about the money.

Confused? You’re not alone.

Minaj has had an eventful week. She canceled her appearance on The Ellen Show on Tuesday (May 22) citing “doctor’s orders,” while suggesting she was planning on making an announcement on the show. Her upcoming fourth album, Queen, is scheduled for release June 15.
