Celine Dion will not return to her Las Vegas residency this year. The 'Think Twice' hitmaker postponed her shows at Caesars Palace Hotel and Casino last August to care for her husband René Angélil, who had a cancerous tumour removed from his throat in December 2012, and though she was originally expected to return to performing in March, TMZ reports she has now told the venue she won't be back until the end of 2015 at the earliest. René is said to be getting better and recovering slowly from the disease. When she first cancelled her working commitments, Celine spoke of her desire to dedicate her time to her spouse and their three sons. She said: "I want to devote every ounce of my strength and energy to my husband's healing, and to do so, it's important for me to dedicate this time to him and to our children. I also want to apologise to all my fans everywhere, for inconveniencing them, and I thank them so much for their love and support ... at this very difficult and stressful time. .
