She thinks she can sell like a white celeb and it doesn't work that way. George Clooney has various products, some of which he promotes but many he doesn't. You just see an article that he has a new wine or liquor coming out, see a picture of him in Malibu toasting with some rich people...and then a year later you hear that shyt is earning millions in revenue.
White people aren't buying a Beyonce liquor just because it's Beyonce. Especially if she's not lifting a finger to properly promote it. She feels she's above making commercials and doing interviews for her shyt but black markets don't really respond to that silence. You gotta get out there...like Diddy with Ciroc or Hov with his shyt.
In terms of the athletic wear you already know what the stereotype about black women working out is. That seems pretty obvious to me.
