Leave it to Solange Knowles to stir up drama at the Met Gala!
Though the 29-year-old didn't brawl in an elevator, she did raise eyebrows with a tweet shared at 2 a.m.
Fans immediately began speculating over who the mystery guest could be, with the most popular guesses being Kimye and Katy Perry — though one follower suggested Taylor Swift based on a picture taken at the event.
While the tweet certainly stirred up gossip, it wasn't anything compared to Solange and Jay Z's epic elevator fight at The Standard Hotel following the 2014 Met Gala.
