Australian recording artist Iggy Azalea couldn't tell her friends and family she had landed a spot on Beyonce's tour because she was ordered to keep it secret.

The international pop superstar sent her team to catch Azalea's show in Manhattan after being impressed with her during their first encounter at British charity concert Chime for Change.

Beyonce agreed to sign her up as her supporting act on the Down Under leg of her Mrs. Carter Show world tour. However, Azalea was banned from sharing the major accomplishment with her inner circle for six weeks.

The 23 year-old singer tells Billboard, "I met her at Chime for Change, which was a Gucci charity event I did in England with her that she invited me to do.

"After which, I did a few shows here in New York at the Bowery and she sent some of her people down to check out what they thought of my show. Apparently she liked it and they called up the next day and said, 'Do you want to come on tour?' I had to keep it secret for so long, almost six weeks. I was just dying! I'm so excited to go on tour with her, so excited!"

Beyonce heads to Australia in October.
