The 'Whataya Want From Me' star - who is currently taking his 'Glam Nation Tour' across the US - was asked by Capital FM's Rich & Kat if he made his roadies "glam up".
"I don't make anybody glam up but I notice that even our support bands, our opening acts, slowly but surely all the men have started to wear eyeliner and nail polish!" he replied.
"I haven't actually told them to do it, they just start. It's like osmosis!"
He was also asked whether there was anybody on the tour bus who let him down with their lack of sparkles, to which he laughed: "No! It's actually a really cool group. I'm having a great time because of them. It's a family."
Lambert is scheduled to play Cleveland, OH, tonight and will bring his tour to the UK later this year.
