When meeting the most powerful man in the world, it's only natural to muddle your words.
Of course, if you're a YouTube star, then it's more than likely that any mistake in front of the Commander-in-Chief is going to appear on camera.
Thus on Thursday, YouTube sensation Glozell Green - well known for her sharp tongue - got that particular muscle in a twist when she accidentally implied Michelle might not be Barack Obama's first love.
The comedian was nearing the end of a White House interview with Number 44 when she said: "My momma says whenever you go to somebody's house you have to give them something. Don't come empty-handed."
She then handed the president three tubes of green glitter lipstick: a Glozell Green staple.
"One for your first wife…" she said, suddenly realising her mistake (she meant First Lady).
"My first wife!?" Obama quipped. "Do you know something I don’t?"
"I'm sorry," Green said repeatedly, evidently mortified by her mistake.
"I'm teasing,” Obama said laughing.
The White House staged a number of interviews with YouTube stars on Thursday to follow up the policies outlined by the President in the State of the Union address on Tuesday.Reuse content
