The 48-year-old artiste said it was her "B***h Better Have My Money" video that made him pull up his socks and prove himself in the industry, reports FemaleFirst.
"Rihanna (is) dangerous. I had this conversation with (director) Tom Wyatt, prior to this video coming out. He said, 'who do you want to compete with like in music and things like that?'
"I said, 'Rihanna.' (Her) 'B***h Better Have My Money' video? That's a hardcore video," Manson told Zane Lowe on Apple Music's Beats 1 Radio.
The rocker, whose real name is Brian Warner, recently released the video of his single "We Know Where You F***ing Live".
