Sing in Space:-

Global pop star Lady Gaga will soon be performing among the stars, blasting off into outer space in 2015 on a Virgin Galactic ship.

"She has to do a mouth of vocal training because of the atmosphere,"

Gaga may become the first chart-topper to give a concert in orbit, but it won't be the first tune performed in space.

Justin Beiber already has travel tickets on Virgin Galactic.
