SO... here is the underlying issue.
The "public eye". No one should give a D*MN about the public eye. Real talk.
But for the sake of argument, let's say we do care. Now... do you believe a public divorce will drop your album sales? Perhaps loose you money and publicity?
Or do you believe that there are a billion not so smart men and women out here in the world that will STILL relate to you in this way? Heck you may even GAIN followers/fans due to this.
There is NO reason to stay with anyone who cheats on you.
YOU are worth more, even if you already have billions.
