First she gave Madonna an open-mouth kiss, now peppery provocateur Britney Spears says she’s a “little bitter” about men.
But she’s not a lesbian, she insists. Not that there’s anything wrong with that.

The 21-year-old pop princess opens her mouth again to Newsweek, in which she pouts a lot about Justin Timberlake bedding her and blabbing about it.

“It was really hard,” she said of her breakup with the ‘N Sync heartthrob. “There was a time when I was like, ‘Okay, I’m over men. They’re mean.'”

The gum-smacking chart-topper said she swore off men for six months after her split with tattletale Timberlake.

“Not like they weren’t drawn to me, but there wasn’t a single real attraction,” Spears said. “I’m like, ‘What’s happening? I know I’m not lesbian.'”

The “Oops! … I Did it Again” singer had maintained that she was a virgin before and during her relationship with Timberlake. Now, she says, what’s the point in fibbing?

“Justin said it on Barbara Walters,” Spears griped. “The world knew after he told them all. What am I supposed to say, ‘No, I didn’t?’ Can you say I’m a little bitter with men? Just a little.”

The Louisiana-born Lolita asked as many questions as she answers in the magazine article, which hits newsstands today. She most wants to know why the wife of Maryland’s governor is threatening her.

Kendel Ehrlich made headlines earlier this month by telling a mostly mothers crowd: “If I had an opportunity to shoot Britney Spears, I think I would.”

The menacing comment, which Ehrlich later said was a joke, was prompted in part by Spears’ Aug. 28 lip-lock with Madonna on MTV’s “Video Music Awards,” and her libido-driven lyrics.

“Why? Why are they mad at me?” asked Spears, who recently posed topless for Rolling Stone and bottomless for Esquire.

“What is too sexy to them?” Spears asked. “My family, we walked around the house naked. … By the time I was 13, my dad was like, ‘Uh, Britney, it’s time to start covering yourself up.’ I’m very free like that.”

Spears said deep down, she’s just like any single heterosexual gal: She wants to meet Mr. Right and have kids – who she does not want emulating her style.

“Not that it’s dirty or tacky, but it is really revealing and I wouldn’t want my kid, at 21, to be dressing like that,” she advised.
