Do we already know who will play the next Fortnite concert? Donald Mustard added a hint himself

Since yesterday, there has been a very big discussion about a potential artist who may soon play a concert in Fortnite.
Concerts have become a permanent element of Fortnite, although this season it will be quite difficult to make them. All because there is a fight going on on the island, so the concert will not fit the plot very well.
In any case, the mass of people responsible for leaks report that the next singer to appear in Fortnite will be Billie Eilish. It’s quite surprising that subsequent Twitter profiles take it for sure.

According to those dealing with leaks, the confirmation of the concert was on the profile of Donald Mustard, who himself was at the concert with his daughters and spoke very favorably about the singer.
Can Mustard’s entry be treated as a trailer? Yes and no. After all, Donald could just go to the concert and that was it. On the other hand, he loves to add such non-obvious hints and it would not be the first time that there is a cooperation trailer on his profile.
