Britney`s got another fashion blunder under her belt. The singer, 28, hit the Grammys Sunday in a bizarre black, long-sleeve lace dress with black body suit by Dolce & Gabbana. Even though the "Womanizer" singer lost out to Lady Gaga in the Best Dance Recording category, she appeared to be in good spirits. (E!`s Ryan Seacrest noted that she "ran by" him on the red carpet with "an entourage of 100.") "On my way to the Grammys," Spears Twittered before the show. "Can`t wait to see all the performances!"
