Lady Gaga set to make history in 2015 as the first singer to perform in outer space

She has pushed the boundaries with her wacky outfits and bizarre behavior.

And now Lady Gaga will be charting new territory of an entirely different kind.

The 27-year-old will make history in 2015 as the first singer to perform in outer space.

The Applause hitmaker will embark on a space mission with Virgin Galactic flights and is reportedly planning to have vocal training to ensure she can still hit the correct notes in a gravity-free environment.

'She has to do a month of vocal training because of the atmosphere.

 '[This will be] like nothing the world has seen before.'

The star will perform on the third day of the Zero G Colony festival which takes place at Spaceport America in New Mexico approximately six months after the first Virgin Galactic commercial flight, and has taken the necessary precautions to ensure she is protected against the worst possible outcome.

'Gaga has taken out a ridiculous life insurance policy,' said the source.

Sir Richard Branson's Virgin Galactic Program launches next year and a list of stars including Ashton Kutcher and his girlfriend Mila Kunis, Justin Bieber and Leonardo DiCaprio have confirmed they have bought seats to fly to space for $250,000 each.
