Katy Perry may be more famous for her huge boobs than her singing voice, but she accidentally gave the world a glimpse of an equally valuable asset on Monday when she mistakenly flashed her a*s, thanks to a pair of ill-fitting bikini bottoms.

First things first: you can check out the epic photo here. Ya done? Alright, now we can comment:

1.) Dayuuuuuum! Who knew that Katy was rockin’ an epic white girl booty all this time? We’ve been so focused on her giant rack and awful relationships all these years that we totally failed to notice what was going on ’round back.

2.) This is what you get for buying bikinis off the discount rack at Lane Bryant, Katy. Look at the tag hanging off that thing! You could sail a boat with it! Check your tags, shorty. You’ve certainly had no problem finding form fitting bras over the years.
