Oof. We never thought we'd see songstresses like Katy Perry, Beyonce and Adele in our 2013 Grammys worst dressed pictures recap, but alas, even the most fashionable celebs have their weak moments. C'mon gals! You're better than this...

Katy Perry showed up in a shade of green that made us think "pea soup 'Exorcist' puke." Or maybe it was more half-chewed winterfresh gum? Either way, it was bad and a huge eye sore the entire evening. Luckily, her gigantic boobs were totally out, so that was a nice distraction. Unless you're a hater of mega-sized boobs, then you probably were like, "Ew. Get those things out of my face."

Then there's Beyonce, who just disappointed us with her casual black and white top and black pants. What gives, Bey? You rock gowns and glitzy dresses almost on the reg, and you show up to the biggest award show in music wearing pants? Tsk, tsk.

While we're on the subject of huge disappointments, may God curse the stylist who put Adele in that flower bomb of a dress. The pattern reminds us of bad '70s wallpaper, and the shape and length aren't really doing it for us either. We love that Adele went for something other than black, but this look made us want to cry more than '21' did.

Further down we've got Carly Rae Jepsen, who you can almost always count on for a lousy red carpet look. It's a real shame that she looks so disheveled in her black dress and messy makeup, since she's a cute girl and really has the potential to look great. Finally, there's hit-or-miss fashionista Florence Welch, who unfortunately, had a miss at the 2013 Grammys with her zombie-inspired makeup (maybe it was a tribute since she was missing 'The Walking Dead' tonight) and 'Teenage Mutant Ninja Turtle' meets Bowser sparkler.

Who do you think was the worst dressed at the 2013 Grammys? Vote below, or leave a comment if you disagree with our picks.
