She also caused a stir back in April when she shaved her hair off, prompting strong reactions from fans who objected to the new hairdo, as well as from ones who liked her new look.

The singer later explained that the decision to shave her head was not a spiritual issue, but that her hair was simply too damaged and she wanted to start anew.

The Australian-based Hillsong Worship has helped shape praise and worship over the last two decades with its catalog of songs that are being sung by an estimated 50 million churchgoers worldwide each week.

Smith, who has been the female face for Hillsong music for the last few years, has said that she is in awe that God had taken a group of people from different walks of life and brought them together to make use of their gifts to make an impact.

"God is completely in control and He interweaves things if you completely surrender and trust Him. He actually has good things for you and you can trust Him," she said in a previous interview.
