The flamboyant pop star is fascinated by the mythical creature - which is typically depicted as a white horse with a single, straight horn growing from its forehead - because it is different and contains "magic".
The `Born This Way` singer said: "I-m actually quite obsessedwithunicorns. They are in essence a mythical creature. The unicorn is born magical and it`s not the unicorn`s fault and it doesn`t make it any more or less special or any less unique but it can`t help that it was born with that magic."
The eccentric musician believes her fascination with the creatures comes from her love of My Little Pony toys - miniature multi-coloured horses that also included ranges of unicorns and Pegasi, flying horses - when she was a child
Speaking on the `Big Top 40` radio show in the UK, she added: "I had My Little Ponies. I was obsessedwith the idea of a creature that was born with something magical that sort of made them the misfit in the world of the stallion."
The 24-year-old singer is believed to be including a track entitled `Unicorn` on her upcoming album `Born This Way`, although it has not yet been confirmed if the song will make the final LP.
