The "Dope" performer, 27, is set to blast off in a Virgin Galactic ship and belt out a single track during the Zero G Colony tech festival in New Mexico.

"She has to do a month of vocal training because of the atmosphere," says a source, who adds that the diva's glam squad will join her in the shuttle.

Zero G Colony is a three-day hi-tech festival set to take place at Spaceport America in New Mexico that features world-class entertainment and cutting-edge technology.
