Celine Dion has postponed her return to her Las Vegas residency to the end of 2015. The singer was expected to resume her gig in Caesars Palace in March but informed the venue that the earliest period she might return would be by the end of the year. No specific date was given, according to TMZ.

The 46 year old singer took a hiatus from her shows at the Caesar Palace Hotel and Casino last August to care for ailing Rene Angelil, her husband of more than 20 years.

Angelil was diagnosed with throat cancer and had undergone surgery to have the cancerous tumor removed.  Sources close to the couple have shared that Celine's husband was getting better.

When Celine initially cancelled her working commitments, she expressed the desire to dedicate more time to her husband and their three sons. They have three children together.

"I want to devote every ounce and strength 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 apologize to my fans everywhere, for inconveniencing, and I thank you so much for their love and support at this very difficult and stressful time," Celine said in an interview.

Dion met Angelil in 1980 when she sent him her mixed tape demo. Angelil became her manager and they eventually got married in 1994.

Angelil recently resigned from his position as his wife's manager after the surgery. He officially handed the position to Aldo Giampolo, a long-time friend and collaborator.  Giampolo has worked with Angelil and Dion for 20 years.
