Céline Dion is back to performing just three weeks after her husband René Angélil's death, but she's still grieving. The "My Heart Will Go On" singer took to the stage in Las Vegas Wednesday, wowing audiences with her powerful voice thanks largely in part to her deceased beau's "strength and warmth."

People magazine reports that Dion, 47, was brought to tears during her show at The Colosseum at Caesars Palace, which she called her "home away from home." The Grammy-winner thanked her fans for their support following Angelil's passing on Jan. 14. She added that she could feel him surrounding her, pushing her to perform. Dion claimed her husband of 21 years was coming through to her via the audience members, stating that she could feel the love he had for her shining through each of them. 

"I feel his love in this room," she said. "I feel his strength and his warmth being reflected in all of you. René always surrounded me with the best people who believed in us and always worked so hard on our behalf."

Angelil isn't the only person Dion's been forced to say goodbye to in recent weeks. On Jan. 16, just days after her husband's passing, Dion's brother Daniel lost his battle with cancer. According to TMZ, he had been battling brain, tongue and throat cancer. He was hospitalized on Jan. 15 at which time doctors claimed he had just "days and hours" to live.

Dion's husband, 73, died in the early hours of Jan. 14. He was diagnosed with throat cancer for the first time in 1999. The disease came and went several times before his death. Angelil's funeral took place at the Notre-Dame Basilica in Montreal the week after he died, Today reported.
