Celine Dion's late husband Rene Angelil is not only the father of her three children, but the only man she has ever kissed romantically.

The 48-year-old singer opened up to CBS News in a new interview about her landmark 1,000th performance in Las Vegas this past Friday, and talked about still mourning Angelil's death in January after a long battle with throat cancer. The two met when Dion was 12 years old, and were married for 21 years.

"Before he left, it was very, very difficult for all of us," Dion says. "For me especially, and my children, to see the man of my life die a little bit more every day. And when he left, it was kind of a relief for me that the man that I love, the only man that I kissed, the only man that I loved ... . I never kissed another man in my life."

"So the man of my life was my partner, and we were one," she continues. "So when he stopped suffering, I said to myself, 'he's OK.' And he deserves not to suffer."

Angelil was 26 years Dion's senior. The "My Heart Will Go On" singer recalls her very first impression of the music manager.

"I thought he was very beautiful," she says. "He looked great. I felt confident that this man was not treating me as a, 'Oh, hi, little pumpkin.' Or, 'Hi, little sweetie,' or like a little baby."

Dion says she's not looking for love anytime soon, and is still "in love" with Angelil.

"I love him. I'm still in love with him," Dion says. "And I have the love of my children. I have the love of my fans. I love the people that I work with. So my life is not empty of love."

"But there's a song from Sia, 'I go to sleep and imagine that you’re there with me.' And I go to bed with him," she adds. "And I come on stage with him. And so I'm still married to him."

ET spoke with Dion in July at rehearsals for her concert at the AccorHotels Arena in Paris, France, when she revealed another superstar singer that's helping her cope with her big loss this year -- Pink. Dion exclusively revealed to ET that Pink wrote a song for her --  which she debuted last month -- in honor of Angelil.

"It's called 'Recovering,'" the five-time GRAMMY winner revealed. "She is phenomenal. I love her for her talent, for her strength, for her focus, the person she is. At the [Billboard Music Awards] when I saw her, I said, 'For you to take the time to really write a song, to give me a tool, a piece of luggage to help me to move forward to walk to keep going…"
