Lady GaGa feels ''honoured'' to perform in space.

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.''
