Greyson Chance is slamming Ellen DeGeneres in a new interview with 'Rolling Stone.’ The musician details his once close relationship with the former host and their fallout. Greyson's relationship with Ellen started over a decade ago after he went viral when he performed Lady Gaga's 'Paparazzi' in 2010 as a 12-year-old. Within a week, he traveled to L.A. to appear on the show. But as Greyson recalled his time with her, he referred to Ellen as 'domineering’ and ‘controlling.' The 25-year-old also called her an 'insanely manipulative person.'
