Edge of Seventeen: Miley Cyrus, Jamie Lynn, Ali Lohan

We are all too familiar with the hard-partying, promiscuous, trouble-making Hollywood set that includes Paris Hilton, Lindsay Lohan, Britney Spears and countless others. What you didn't know? They're already being replaced by a new batch of youngsters willing and able to up the ante.

Leading the pack is Miley Cyrus, the 15-year-old pop sensation that yields about as much power these days as Oprah. The family-oriented Disney star may preach to be saving herself for marriage, but day after day more scandalous images (see above) and factoids work their way into the press, and it's making us question just how devout the teen really is. Which leads us to...

Jamie Lynn Spears, Britney's newly-17-year-old sis who is just months shy of having a baby we can only guess was unplanned. Miley and Jamie Lynn's mothers had a heart-to-heart several months ago at Starbucks to swap advice. Not so sure it's working, ladies!

But Jamie Lynn isn't the only teen star to learn by (bad) example. Lindsay Lohan's kid sister Ali has just begun filming her first movie at 14 and was propelled into a Lohan family reality show by her I-don't-wanna-grow-up mom, Dina. "I grew up watching Lindsay, and it made me want to do what she does," Ali recently told Teen Vogue. " Being there, being on camera, or onstage, with everybody listening to you…it's so cool when people look up to you. I want it so bad. So bad you don't even know." Wow, can you spell L-O-S-T C-A-U-S-E?

Last but not least we have Emma Watson, the Harry Potter star who just got her little hands on her big ($20 million!) fortune last week when she turned 18. The pics on the internet of her boozing it up underage and more recent classic getting-out-of-the-car-panty-shots remind us of the Britneys and Lindsays of yesteryear. Uh oh, looks like history repeating itself-only this time, they're younger.

Do you think female celebs today have gotten overly racy and if so, do you think this has to do with the infiltration of media and the accessibility of digital pictures on the Internet?
