After catching a bit of flack for meeting with the Canadian Prime Minister in a decidedly casual pair of overalls, Justin Bieber took to Instagram Sunday to explain himself.

"The pic of me and the Prime Minister was taken in a room in the arena where I was performing at that day," Bieber wrote in response to a journalist who criticized the move as "white trash."

"I walked straight from my meet and greet to him," he explained further. "It wasn't like it was like I was going into his environment we were at a hockey arena. Wow am I ever white trash."

The superstar (seen above) was snapped in Canada this week to accept a Diamond Jubilee Medal from the leader of his home country, Stephen Harper.
