ET's Steven "Cojo" Cojocaru had some tough fashion choices to make at the 53rd Annual Grammy Awards as he compiled his Best and Worst Dressed list.

In at No. 5 was Katy Perry in "the wildest thing Armani has ever done." He called her an "angel from the fashion heavens."

Cojo's No. 4 pick was "Glee" gal Dianna Agron in Vivienne Westwood who he referred to as "sublime."

His No. 3 spot went to the always fashionably loud Nicki Minaj in Givenchy who showed up looking more outlandish than ever. "Thank you Nicki for getting it," he said of the pop star. "You gave us wild, you gave us leopard, a leopard never changes its spots."

The No. 2 star on the best dressed was styled completely differently than Nicki. Jennifer Hudson arrived to the Grammys looking super svelte in a Versace gown. "You're the Grammys' glamorous transformation of all time," he told the singer/actress.

Check out the video to see who topped Cojo's Best Dressed list and who had the fashionista singing "Baby, baby, baby, noooo!"
