She joins stars including David Bowie and Diana Ross who have been honoured with a doll as part of the Barbie signature series. Marking almost four decades since the track was first released, as well as Houston's birthday, the doll honours the singer and her legacy in music, entertainment and culture. "Whitney Houston's music has been the soundtrack to countless moments for fans around the world," Mattel's Barbie vice president Nathan Baynard said. The doll was unveiled during the 5th annual Whitney Houston Legacy of Love gala, held to benefit the late singer's foundation aimed at helping young people. She was behind hits including How Will I Know, Saving All My Love For You and her chart-topping rendition of I Will Always Love You.
