Kelly Clarkson shares her rigid cleaning routine and a friend she considers a ‘serial killer'

Singer-songwriter Kelly Clarkson has just dished on the ‘serial killer’ level of cleanliness Clay Aiken maintains.

She started the entire thing by admitting that she also finds the act ‘theraputic’ but added that Aiken takes it to an ‘extreme degree’.

According to Variety, she talked at length on yesterday’s episode of the Kelly Clarkson Show and saw one of her guests, Norman Reedus admit, “I'm really kind of anal about stuff like that.”

“You would look at me and never think that, but like, my refrigerator, the yogurts have to be right there in order. I'm that guy. You would never know,” the Wednesday actor noted further alongside Ian McShane.

It was at this point that Clarkson chimed in and revealed one other name that she considers a ‘serial killer’ level cleaner.

Recounting it all she admitted to having “had a friend like you that I used to mess with,” one person that “looked like a serial killer with his refrigerator.”

The name of that friend was “Clay Aiken. He was on [American Idol], the same show I came from, and I went to his house, and I was like, 'The hell?'”

“He had everything so, and then just to f**** with him, I just moved everything. And it did mess him up. It did look like a serial killer lived there, how his refrigerator looked.”
