It's no surprise that the mums have turned out in force to chaperone their kids at Britney Spears' show at Tokyo Dome: They've seen her recent, more raunchy videos, witnessed her fondling a huge snake during her performance at the MTV video awards and noticed that on her third and latest album, "Britney," she's cut down on the "oops" and "babys" and introduced words such as "hell" and "damn." Something's up, surely, and they want to be on hand to find out exactly what.

No longer the cute, innocent girl-next-door whose worst sin (apart from ex-boyfriend Justine Timberlake) is a navel piercing, Britney tonight gives her Japanese fans a show that is maybe better-suited for the grown-ups than the kids, and a little more Marilyn Manson than teen idol.

OK, it's hardly "Britney Live -- Welcome to Hell," but, having turned 20, the singer is desperate to show us she's no longer a girl. Instead, she's decided to be a little devil and dabble in some dark stuff.
