The world isn't done reckoning with Michael Jackson. And that includes those who knew him IRL... Mark Ronson is the latest to take a hard look at his time with the music legend - a relationship made all the more unsettling because at the time, the Uptown Funk artist was just 13 years old... The Oscar-winning songwriter has collaborated with the likes of Lady GaGa, Bruno Mars, Adele, Miley Cyrus, and more of the industry's finest... But way back when he had an encounter with MJ that was not so professional. And in his new book, he's finally opening up about it.
