Lady Gaga to sing in outer space in 2015?

New York: Pop sensation Lady Gaga has reportedly signed up to perform one song in space as part of the Zero G Colony high-tech musical festival in 2015.

The mysterious festival will take place over three days at New Mexico`s Spaceport America.

The 27-year-old `Applause` hitmaker performance is said to be planned for the third day of the concert series at dawn, reported the New York Daily News.

"She has to do a month of vocal training because of the atmosphere. Gaga has taken out a ridiculous life insurance policy!," a source said.

The event will mark the first time that a pop artiste has performed in space.

Gaga, who will be boarding Richard Branson`s `Virgin Galactic` ship, is not the only pop star with plans to explore the final frontier.

Justin Bieber, Katy Perry, Rihanna and Lance Bass have all signed up to take a ride on the Virgin Galactic ship when it launches.
