The guys talked about their most embarrassing performance. "It was in Miami, " Howie went on to say it was a "foam party" and a wet t-shirt contest. When they went out on stage to perform the guys in front of the stage were expecting the contest, not the Backstreet Boys.
Howie, Nick, AJ, Brian and Kevin performed "Madeleine", "In A World Like This" among others, and answered fan questions. When a fan asked what their favorite Backstreet Boys song of all time was, Nick jokingly answered, "That's What Makes You Beautiful," giving a nod to One Direction.
Watch them talk about the coolest thing a fan has ever done for them, and wanting to perform in front of the pyramids in Egypt. AJ even admitted to using mascara back in the day to paint on his beard below!
