Lady GaGa's friends will visit her in Sydney[Photo/Agencies]

Lady GaGa is flying her friends out to visit her on tour.

The 'Marry The Night' singer plans to jet 20 of her closest companions from the United States to Australia.

The 26-year-old pop star is making the kind gesture - which will see her loved ones attend her June 21 concert in Sydney - as is reportedly lonely on tour.

A source told The Sun: "When touring, she misses her friends desperately.

"She speaks to most as much as she can but it's difficult with the time difference, rehearsals and performances."

Meanwhile she recently vowed to perform "alone" if she has to in Jakarta.

The 'Judas' hitmaker's Indonesian show - set to be the biggest in her Born This Way Ball tour's Asian leg - is in jeopardy after protests led police to refuse a licence for it to go ahead, but she has not given up hope of staging a show in the nation.
