Simon Cowell keeps weights and mouthwash in his 'Britain's Got Talent' toilet.
The music mogul's bizarre bathroom habits have been revealed by fellow judge Amanda Holden, who thinks he likes to workout with the equipment and refresh his breath at the same time.
Speaking on chat show 'Alan Carr: Chatty Man', Amanda said: "We always get designated a judge's toilet for 'BGT'. Simon keeps a little bottle of Listerine in his.
"There are also weights - I think he gargles and lifts at the same time."
Amanda, 42, also claimed to have nearly spotted the 53-year-old star's manhood when he went commando while filming the show, much to the disgust of fellow panellist David Walliams.
"When I told David, he said, 'That's terrible, Simon, you only wear those jeans all week'. He wears no pants and the same jeans.
"He wears no underwear and the same jeans."
Comedian David, 41, recently became a father for the first time after his wife Lara Stone, 29, gave birth last weekend – and Amanda is surprised at how much their newborn son resembles Simon rather than the funnyman, joking her fellow 'BGT' judges are the real parents after forming a bromance while working together.
She added: "I said he looks more like Simon. They're going to make brilliant dads. I think they put it all in a test tube, gave it a little shake and Lara took it.
"Simon has been fighting David but behind closed doors they love each other. Simon tries really hard to fight it but he has given in to 'The David'.
"I like watching it. They don't have many real men friends in real life. So I think what has happened they have ended up being good friends."
