When Britney started out she said Whitney Houston was always her favorite singer and that she looked up to her more than anyone else. Well, ever since her and Madonna have become new best friends, every interview Britney has done says how Madonna was who she has always looked up to the most.
Same goes for Christina. In the early days, Christina would always say that Mariah was who she looked up to most and wanted to be like. Then ever since she performed for Whitney and the BET awards and met Whitney she says Whitney is who she always looked up to the most.
I mean, obviously Britney was influenced by Madonna when she was younger and Christina by Whitney....it is just interesting to me how they changed their minds about who was MOST influencial after being able to meet certain divas.
