(Cover) - EN Star Style - Christina Aguileras style icon is Rihanna because shes tough but sexy.

Singer-and-actress Christina is considered somewhat of a style icon herself, thanks to her outrageous on-stage costumes and daring make-up choices.

The blonde beauty, 29, admits shes inspired by fellow pop star Rihanna, as she loves how the 22-year-old fashionista isnt worried about what other people think.

[I really admire] Rihanna. She exudes a confidence and is not afraid to be tough. She gives off a take-charge persona and I find that sexy, enthused Christina in an interview with the American edition of OK! magazine.

In her early career, Christina was famed for her overtly sexual dance routines and raunchy outfits, but nowadays shes matured and says she has a more refined sex appeal. Christina has a two-year-old son Max with her estranged-husband Jordan Bratman, and says her sexuality entered a new stage when she became a mother.

I have more confidence in my sexuality it has a more sophisticated tone. Sexuality has always been a part of what I do, but having a child has changed me in so many ways. I have my body back, but in a completely different way, she added. (C) Cover Media
