Cojo Dishes on the Met Gala's Worst Dressed Star

On a night known for fashion, not everyone dressed to impress, according to ET's Steven "Cojo" Cojocaru, who berated one star for showing up at the Met Costume Institute Gala dressed "like a flying saucer."

Cojo bestowed his worst dressed crown to Beyonce, who appeared in a black and gold Emilio Pucci gown.

"This time wasn't good," Cojo said of the frock. The fashion guru went on to end his rant on a more hopeful note, saying, "There's always the future."

Cojo wasn't the only one displeased with the music diva on Monday night. As she arrived for the event honoring late fashion designer Alexander McQueen, Beyonce received boos from paparazzi after she supposedly didn't stop long enough to please photographers.

Cojo's best dressed honor went to another music diva -- Madonna, who wore Stella McCartney.

Following Madge in Cojo's ranking of the night were Penelope Cruz in Oscar de la Renta, a pregnant Kate Hudson in Stella McCartney, Gwyneth Paltrow, also in Stella McCartney and Taylor Swift in J. Mendel.
