The 'My Heart Will Go On' singer appears in V's upcoming travel issue wearing just long black gloves and tight trousers, while covering her chest with her arms.
She explained that the shoot is not something she would normally do, but that she was "glad" about her decision to try it.
"I'm like this in my real life," she said. "I was scared a little bit because this is so different for me, but I'm glad I did it. Usually there's always a reason when I do a photoshoot, there's not the opportunity to go crazy."
Talking about her long career, she stated that her success is down to showing fans her real personality on stage.
"I've been an open book all my life and I think that's why people like me," she said. "For me to tell someone that my husband [René Angélil] had cancer, that we were struggling to have kids, or whatever we've gone through, talking about my life lets people know the real me."
Celine Dion recently praised British singer Adele, describing her as "refreshing".
She is rumoured to be planning two albums for release later this year.
