A giant printed ponch, a peek-a-boo crop top and a crazy cutout gown -- stars are rocking all the wrong trends this week!

Anne Hathaway is known for her elegant red carpet style, but she landed on the worst dressed this week for sporting a giant aztec-printed poncho after an appearance on "Good Morning America" on Tuesday. The actress added even more pattern with a black-and-white, checkered handbag, completing her bizarre ensemble with thick round-framed glasses. Time for a new stylist!

Naya Rivera raised some eyebrows on the red carpet at Marie Claire's Fresh Faces Party on Tuesday, rocking a cream Philosophy top with a very open slit down the side, black grunge-inspired capri pants and black stilettos. We know she loves to show off her killer bod, but it looks like she cut that slit herself.

And Shakira caught everyone's attention at the Academy of Country Music Awards on Sunday -- and not in a good way. The singer donned a forest green Zuhair Murad gown with crazy cutouts along her midsection and thighs. The details reminded us of a giant spider web -- which is not an attractive red carpet accessory.

But they weren't alone -- see more of this week's worst dressed stars in the gallery above.
