"I feel happy, I feel beautiful" - Celine Dion says as she graces the cover of Elle Magazine

Celine Dion is the cover star of Elle Magazine June issue.

The 51-year-old singer models Valentino Haute Couture on a special subscriber cover of the magazine as she talks about life over 50 and her new-found confidence.

The new spokesperson for L’Oréal Paris says the cosmetic giant's 'I'm Worth It' tagline really resonates with her.

She tells Elle: 'Telling other women that they, too, have self-worth, that they are strong, is obviously really important. You cannot limit yourself.

'My life started over at 50; I feel happy, I feel beautiful. I thought, "I must have done something right for this to be happening."

'I love fashion a lot, definitely. For me, fashion is art. It's a way of expressing yourself. When I put something on, I play. I don’t take myself seriously. I kind of, like, borrow a character. But to be considered a fashion icon? 'I don't know, I just do one day at a time, do the best I can, feel the way that I want to feel. That's the most important thing.

'With over 3 million followers on Instagram the Canadian megastar could be forgiven for checking up on her likes and comments... but she tells Elle she really doesn't care too much.

'I am like a one-year-old!' she says. 'I'm not saying that I don't care what people think of me, but I've reached a point in my life where I can let myself make my own decisions and choices.

'Now I am discovering myself more and more. I am a woman assuming her own destiny, full of energy and in love with life. It's never too late to start. At 51, I have the sense that I am at my pinnacle!'

The last night of her Las Vegas residency is fast approaching on June 8 marking 16 years since she first opened at the Colosseum at Caesars Palace - which was specifically constructed for Céline’s first Vegas outing, A New Day.

She says the end of Céline is 'bittersweet, because it is a closure.

'This whole project started as a dream for René and me, but you know what? It’s a book. And in life, there are many books. So maybe we’ll meet again and talk about the next book, I hope?'
