Nicki Minaj has been laying low – really low.

No solo music, no big appearances and a virtual no-show on social media this year.

A Sunday tweet from Minaj sent her fans into alert mode!

Nicki simply tweeted the number “4.” That’s it. The tweet was deleted 4 minutes later.

Fans speculated that it could be in reference to a potential fourth album that’s been talked about for this year. It could have simply been itchy twitter fingers too.

What do you think it was?
