The 'Judas' star admits she feels "nervous" as she gets ready to kick off world jaunt.

Lady Gaga has unveiled a special Monster Pit neckless that will be given to one fan at each 'Born This Way Ball' tour date.

The singer is due to begin her massive world tour in South Korea tonight (27th April) and has admitted she feels "nervous" ahead of the show.

In a message on Twitter, Lady Gaga revealed that the first fan in the queue at each tour date will receive one of 110 necklesses. The Monster Pit is located in front of the stage at each show and will be filled with fans who queued the longest to see the star.

"This is a necklace I'll give to the first monster in line every night at the Ball. It's a symbol of the 'key' that opens the pit every night," the singer wrote.

"The real monster pit key will be signed by this fan and returned to me. There'll be 110 necklaces&signatures Mar. 2013."
