This should not come as a surprise to her ardent fans though as she was spotted out and about in Paris, in January this year wearing a shirt with the famous L'oreal line "I am worth it".
The singer had his to say about her endorsement.....
"When I was young, I had problems with my teeth and was very, very skinny," she explained. "I was bullied at school, so I never thought one day I'd be asked to be an ambassador for L'Oréal Paris, the biggest brand in the world for over 100 years. And at 51 years old?"
"The world is changing and L'Oréal is part of that for women. "Your twenties and thirties [are] wonderful and all that, but I would not go back," she said. "As a singer, daughter, sister, friend, [and] partner, I've never felt [so] beautiful and strong. I really think the best is yet to come."
The campaign is set to premiere world wide on April 22.
