The 'Born this Way' hitmaker is set to sing outside of the Earth's atmosphere next year following the launch of Sir Richard Branson's Virgin Galactic commercial space flights - which will cost $250,000 per seat - and she is looking forward to using the opportunity to spread a "message of love".
She said: " I honestly can't wait [to perform in space]. I can't wait to design the performance. I'm auctioning off my second seat [on a Virgin Galactic flight] to raise money for the Born This Way Foundation. I want to make a moment that is about much more than me.
"Performing in space is such an honour. I want to challenge myself to come up with something that will not only bring everyone together but will also have a message of love that blasts into the beyond."
Because of her hectic schedule, the 27-year-old singer - who is in a relationship with actor Taylor Kinney - says she doesn't have a permanent home and mostly uses her New York apartment to keep her expensive belongings.
Asked where she calls home, she told Harper's Bazaar magazine: "My 'home' is a controversial topic. I don't exactly have one. I live all over the world. I keep a small rental in New York, where I hang many of my hats when I come to see my parents and New York pals. It's like a tiny jewel box, covered in rose-gold mirrors, with an oversize pink couch, an expensive vase, a white Marilyn piano, and a boudoir.
"I do not keep a lot of clothes here - mostly punk wear. And the three most expensive items I've ever purchased, including an actual house: my sable, a strand of diamonds, and my Mikimoto pearls."
