"The Thriller star was invited with his children and entourage to Bahrain, shortly after he was acquitted of child molestation charges in California.

While there, the sheikh lavished money on him.

Sheikh Abdulla also built a recording studio, which he believed would be used to record albums using material he had helped to write."

HELLO? HELLO? THE REAL WORLD IS CALLING, IT'S CONFUSED.
