Lady Gaga unveils "flying dress" at NYC album party

Lady Gaga's album sales are already stratospheric, so why not her evening wear?

The "Applause" singer unveiled a high-tech, white vehicle she calls the world's first flying dress. The contraption lifted her inside a mammoth building in New York City, where she held a launch party for her new album Sunday.

The 27-year-old Grammy-winner said this was "maybe a small step for Volantis" -- as she calls the battery-powered metal dress -- but "a big-time step" for Lady Gaga.

She says her ultimate goal is to stage the first musical performance from space (a feat that she is already planning to do).

Her third studio album, "Artpop," will be released worldwide Monday.
