Soul legend Diana Ross has offered to give advice on how to enjoy a long career to superstars including Beyonce Knowles, Alicia Keys and Mariah Carey. The 62-year-old has enjoyed more than 40 successful years in the music industry and is keen to pass her wisdom onto the current generation of female artists. Ross says, "I was getting ready to give advice and support to any of them that wants that. Because Mariah Carey used to always ask, when I would spend time with her, how to have longevity. "So I am available to discuss what it takes."
