Celine Dion's ''spiritual'' belief has helped her cope with her husband's cancer battle.

The 47-year-old singer's spouse René Angélil, 73, has been battling throat cancer since December 2013, after developing the illness for a second time.

Rene's treatment and fight has been very hard on Celine and the couple's three children - 14-year-old son, Rene, and four-year-old fraternal twins Eddy and Nelson - but she has been able to find perspective and strength from her ''spirituality''.

Speaking to Taste of Life magazine, Celine - who was raised a Roman Catholic - revealed: ''Life is not always perfect. You have to deal with it. Whatever life imposes - sickness, or whatever, you don't have a choice. This is life, this is nature. But you do have the choice on how you're going to go through this. And if you don't have spirituality you're going to fall apart before things happen. I am very spiritual. I believe in myself, I believe in my family, and I'm positive. Through this, you show your children how to deal with things, and how to be strong.''

Celine took a break from her residency at The Colosseum at Caesars Palace Las Vegas Hotel and Casino but is due back on stage on August 27.

The 'Loved Me Back to Life' hitmaker's main motivation for returning to work was so her husband can see her perform again and she insists her first performance back will dedicated to the love of her life.

Celine said: ''We are back (in action). We are still together and stronger than ever. René is a champion. I loved him all my life. I don't want to sound pretentious, but I am his favourite singer and he wants to see me back on the stage singing again!''

René was first diagnosed with throat cancer in April 1998 but made a full recovery from the illness before contracting it again 20 months ago.
