Bjork dons alienlike worm dress at Roskilde Festival

If you thought Bjork's swan dress was weird, you ain't seen nothing yet.

The eccentric Icelandic musician slithered onto the stage of Denmark's Roskilde Festival on Sunday in a wormlike dress that was positively writhing.

The 46-year-old concert headliner paired her bizarre frock, created by Dutch designer Iris Van Herpen, with a nest of tangerine-and-blue hair. Bjork's supernatural dress was apt, considering she was performing songs from her new album, "Biophilia."

Never one for following trends, Bjork made fashion history at the 2001 Oscars when she wore a swan dress designed by Macedonian couturier Marjan Pejoski.

The singer was nominated for Best Song for one of her "Dancer in the Dark" tracks, but she lost to Bob Dylan for his song "Things Have Changed" (from the "Wonderboys" soundtrack). Regardless, Bjork was still the talk of the town for her swan dress, which remains one of the most controversial Oscar dresses of all time.

Do you think her new worm dress could become just as iconic?
