"He was [already] wearing the shirt that had his name on my shirt", Mason, 48, told outcome of Sound in a new interview published Wednesday.
"The dark and stormy singer says he told the younger star, "'That was a great idea you had about doing "The Beautiful People" at your show at Staples Center tomorrow.' And he goes, 'Yeah, it was, ' not knowing that I told him an idea that I had just made up.
"Of the interaction, the "Dope Show" singer also told outcome of Sound, "[Bieber] was a real piece of s-t in the way he had the arrogance to say that".
'He was a real touchy-feely guy, too, like, 'Yo yo bro!' and touches you when he's talking.
This, presumably, has been the case for you at some point with Justin Bieber.
Back in 2016, Justin Bieber started selling repurposed Marilyn Manson shirts for some reason. "[Bieber] believed that I'd show up, because he was that stupid".
"They didn't even fight, they were just like, 'Yeah, we already know, we did wrong, so here's the money.' He was a real piece of s**t in the way he had the arrogance to say that".
Perhaps the lesson here is to never trust selfies that make celebrities look like they're bros.
Justin Bieber storms off stage on the British leg of his objective world tour and Nova presenters Fitzy and Wippa send up Donald Trump in parody video.
The only problem was, Manson apparently never signed off on the T-shirt - and wasn't happy to see the shirt on Bieber when they met for the first time. So stand down son'.
"The next day I told him I'd be at his soundcheck at Staples Center to do 'Beautiful People, " Manson recounts, at which point Bieber confessed that the t-shirt 'was his idea.' Manson never meant to perform with Bieber, but 'he believed that I'd show up, because he was that stupid'.
