Pop diva Mariah Carey denies she has loose sexual morals, instead likening herself to wholesome nanny Mary Poppins.

The Hero star knows she is portrayed as a “ditzy moon” by the media but insists she has high morals when it comes to dating. The 37-year-old says, “It’s a dichotomy, I understand. I understand that people think I’m a ditzy moron.”

The once-married superstar, who has been romantically linked with Yankees captain Derek Jeter and rapper Eminem, warns fans they’d be wrong to think of her as promiscuous, insisting she’s never even had a one-night stand.

She says, “I’m Mary Poppins: I’m what the buttoned-up girls are supposed to be.”
