If this was in Relationships, the wisdom would say, when a man shows you who he is, believe him.
His acceptance speech just confirms that he has almost messianic tendancies - "I feel I have been called by God".. so God would approve? You've a red phone to the man upstairs?
If you go back to his incredibly revealing chat with Graham Norton, his whole purpose in life is to be famous. To be the most known, and the most important.
He probably felt humiliated when he saw that whilst he was laughing, Jada wasn't, and this was how he dealt with it.
I don't care if he was high. I don't care how low the MC goes with the roasting, this is not a man protecting his family. This is not a man defending his wife's honour.
This is a man showing you who he is. Believe him.
