Angélil died in 2016 at the age of 73, and had also been her manager from 1981 to 2014.
Speaking ahead of her concert at Barclaycard Presents British Summer Time in Hyde Park on Friday, she told Magic Radio that she is “very proud” of how she has pushed on with her life since his passing.
“I’m very proud of what my whole team and myself have accomplished since the departure of my husband,” she told host Emma B.
“There’s been a big turnaround, a new chapter. Finishing Las Vegas [residency] was very powerful, exciting, bittersweet.
“But I feel more part of decisions and meetings. In meetings everybody is talking about ‘what do you feel?’ and sharing ideas and putting all the cards on the table. I’ve never done that before.
“So now it’s like being in charge of my life. It makes me feel so strong.”
She’s currently working on new music in preparation for an album release later this year, and she teased that she’s experimenting with different sounds this time around.
“The album sounds very fun, very different and I did try new things,” she promised.
“It’s still me but I have opened my wings to embrace new writers and producers. Just to be open to different sounds and see what it would do inside.
“I’m not doing like an AC DC heavy metal, but there’s different flavours.”
Her live performances continue to earn widespread acclaim, but she said that she’s not currently bringing her children around the world with her.
“When I go on a tour you cannot look at all the dates because you’ll have a breakdown and the tour will not happen. My heart won’t go on,” she quipped.
“Because we’re travelling quicker, I didn’t bring my kids with me for the first time.
“They’re eight and a half years old and they’re getting to be very independent.
“Even when we Skype when I leave for like four days, they have no time. So they say ‘hi Mom you’re in Paris you’re doing great. Okay bye. We love you. We got to go because we’re going fishing, bye bye!’”
