Teen star Miley Cyrus has branded pop-punk rocker Nick Jonas her knight in shining armor - after he helped her battle through the toughest time of her life. Last year the Hannah Montana sensation received terrible news her best pal had died at the age of 13 from cystic fibrosis, but was unable to pay her respects because she was stuck on a U.S. tour.

The 15-year-old describes that time as her hardest, stating the pain made her go "crazy", but insists the Jonas Brothers star's wise words were the catalyst in her emotional recovery.

Cyrus - who has denied claims she is secretly dating the 15-year-old Jonas Brother star - says, "Last year I lost one of my closest friends to cystic fibrosis. She was almost 13 and she passed away while I was on tour so I couldn't go back home when it happened. I kind of went crazy. I couldn't understand why it had happened and I was really upset. I was touring with the Jonas Brothers and Nick said I had to pull myself together and he was right because I was going mad."
