Jennifer Hudson's Oscar Dress 2013 Is A Dazzling Blue Roberto Cavalli Gown (PHOTOS)

Jennifer Hudson has come a long way from that unfortunate, Count Chocula looking, ensemble she wore back in 2007 when accepting her Best Supporting Actress Oscar.

These days the singer/actress is a frequently finding herself on best-dressed lists, and after Sunday night's appearance at the 2013 Oscars J.Hud might make a few more.

The "American Idol" alum turned heads in a metallic blue, body-hugging, long-sleeve Roberto Cavalli creation complete with with a high-slit. The fish scale-looking gown was finished off with a pair of complementing metallic blue Jimmy Choo peep-toe pumps.

"It took three days of fittings, three hours each day to make my decision. It’s a serious decision. My stylist cried tears of joy [when I finally decided]," Jennifer told Ryan Seacrest during the "E! Red Carpet" pre-show.

And not only did she wow on the red carpet, she brought the audience to their feet after a goosebump-inducing performance of "And I'm Telling You I'm Not Going" from her Academy Award-winning role in "Dreamgirls." Simply amazing!

Look at J.Hud's beautiful blue Roberto Cavalli gown for the 2013 Academy Awards.
