Very Very true about some celebrities. I don't usually talk about inside stuff, but I will tell a true story. Long, long, long ago, I wrote a script which was optioned by Steven Seagal's production company. He was at the height of his fame (think Under Siege) and was the hot star of the moment. We met several times on script development and all I will say is it was a most unpleasant experience. His then-wife (Kelly) was the opposite. Kind, charming and humble.
Tyreek is suffering from the same kind of self absorbed delusion. And if he isn't careful, he will be in the same place as Segal is now or worse. Honestly, I would trade him if we could.
