'Mirrors' superstar Justin Timberlake has revealed that meeting the President of the United States of America will go down as one of his favourite moments ever. 

Speaking to Jay Leno earlier this week on 'The Tonight Show', the hitmaker explained that they crossed paths at the white house when Timberlake was rehearsing for a performance and he was overwhelmed by how effortlessly cool Barack Obama was:

"Man, he's the coolest guy I've ever met. Let me just say that. We rehearsed and he had some meeting out of stage, I felt weird, like I'm in his house, this is where he lives, and he's not there! But he shows up in the helicopter and the helicopter lands and the things rolls out and he gets off and it's like."

"The camera operators, the producers, everybody who was rehearsing, we all stopped to watch President Obama and he struts off the thing and it was like dead silent. And I looked at everybody and I said, 'Uh, Daddy's home!'"
