London, December 17: American R&B singer Beyonce Knowles apparently believes that being a diva is not necessary to be a role model for girls and young women, for she has her own definition of female beauty.

The 27-year-old superstar says that she feels neither healthy nor sexy when she's thin.

According to her, the term "bootylicious" is suitable for a woman who is curvy, voluptuous, and possesses a well-shaped and prominent derriere.

"I'm just a pop princess using my butt to save yours," the Daily Express quoted her as saying.

Beyonce, who is married rapper and multi-millionaire music entrepreneur Jay-Z, also understands the difference between a great wedding and a good marriage.

She married Jay-Z, her boyfriend for five years, in a discreet ceremony last spring, which was attended only by their families and closest friends.

"I didn't want a dramatic wedding. People can sometimes put too much emphasis on the big day but it's so temporary; it's gone in a second," she said. (ANI)
