Katy Perry hit the red carpet at the Met Gala on Monday, May 1 wearing a deep crimson custom Maison Martin Margiela gown and headpiece that had jaws dropping. As a co-host of the evening’s event, her entrance was one that stunned. That said, the pop star is known for her outlandish looks, both on and off the stage. Whether it's a practically invisible swimsuit or a bright highlighter yellow mini dress, the singer certainly knows her way around an eye-catching getup.

[post_ads]Ever wonder how Katy manages to get in and out of the looks when she has to go to the bathroom, though? The seemingly logistical nightmare is one that perplexed Ellen DeGeneres, as the talk show host asked the singer that very question on her show that’s set to air on this afternoon (May 16). When asked about the feat, Katy replied, “There was a lot of self-control, practice, and GoGirls.

You know those little contraptions where you then get to urinate standing up?” Ellen told Katy she had no idea what GoGirls were, to which Katy explained, “I’ve used them in several music videos because I always find myself in this predicament where I have a very extravagant, lavish, unrealistic, unpractical costume on. That’s just me, I guess.”
