Beyonce?
 

Is Beyonce a DST? I can't find any information about it on the Delta website, but I just found this picture of her.
She's could just be being goofy, not trying to make a handsign, but I thought I'd ask.

Beyonce is not a member of Delta Sigma Theta.
Many people, including Jay Z, do that sign but they are not members of DST.
