Yes, the 25 year old woman in me knows better than to call a teenage girl a slut, but to hell with it: Miley Cyrus was treating the Jumbotron camera at her Las Vegas show like it was the iSight camera on her Mac Book and she was doing another half-naked pic session for one of those Jonas Brothers.

The video above, which is VERY shaky by the way, flashes to Miley at the :12 mark mugging to the camera whilst squatting and baring some serious cleavage. If it’s not clear why this is totally uncomfortable, listen to the reaction of the girl operating the camera.

Miley isn’t much more promiscuous seeming than your average 16 or 17 year old girl, but let’s face it: Homegirl is a Christian Disney star who’s built her name off being a down home family kinda girl. The thought that Billy Ray was likely back stage watching this (as well as Miley’s older brother Trace, whose band Metro Station is opening for her on tour), quite simply makes me want to vom.

My secret boyfriend Matt Damon and Emily Blunt are in New York City filming The Adjustment Bureau and my man is still lookin’ fine. These photos are worth a gander even if you aren’t equally obsessed with Matty Boy– Blunt’s costume in this scene is adorable (I covet that jacket) and Tim Robbins stops by the set to pal around with Damon. Check it all out in the gallery below…

I’m 37 years old and I’ve never smoked pot.  Believe me, this isn’t the result of some Nancy Reagan pledge I took in the eighth grade.  I just refuse to utilize any substance that makes me have the munchies more than I do every day in my unaltered state.

A Pair of Dicks movie director Kevin Smith — you may remember that he’s the one Jennifer Garner hated – was never much of a stoner.  That is, until he hung out with Seth Rogen last summer.  Now he’s doling out advice to our leaders of tomorrow that basically translates to:  ”Smoke!”

The king of stoner moviemakers, Kevin Smith, never really smoked much marijuana until Seth Rogen talked him into it last summer, he says. Now he sparks up at least three times a day and credits pot for helping him to dig his way out of a creative slump.

Not the sort of advice responsible parents, doctors or educators are likely to embrace, Smith told The Post’s Don Kaplan, “I know you’re supposed to tell kids not to do drugs, but, kids, do it! Do weed! Don’t do the other stuff, but weed is good . . . What you want to do is what I did, build a movie empire and, at age 38, smoke it all away.

…Now, thanks to a steady diet of marijuana, Smith says he’s moved on to greener pastures — writing a new “Batman” comic and directing films he didn’t write, including the upcoming cop buddy flick, “A Pair of Dicks,” with Bruce Willis and Tracy Morgan.  Smith says he’s “just not good” at directing his own stories anymore: “Judd Apatow is way better at being Kevin Smith now than Kevin Smith ever was. So Judd Apatow should do it for a while, and I should figure out something else, and weed has been [bleeping] helpful with that.”

Shit, I’ve been missing out on so much potential creativity by taking this whole sober stance.  I plan to start sparking up immediately to see if it will help me be able to do pottery.  I’ve always wanted to throw a pot; maybe inhaling some is the place to start. Mmm … Fritos!

Here’s a change of speed for you:  Chris Noth and his long-time girlfriend Tara Wilson are engaged and openly admitting it.  These two have been together for a long time — she worked for his NYC bar The Cutting Room and they were a couple as early as 2002 — and also share a son, Orion, who is almost two.

Noth is 54 — I’m pretty sure this is his first marriage which is shocking by Hollywood standards — and Wilson is exactly half his age, natch.

Congrats and good luck to the happy couple!

If the NY Post is to be believed, Penelope Cruz and Javier Bardem are set to tie the knot.  Remember how many times we were told that Jennifer Aniston was marrying Vince Vaughn/ex-husband Brad Pitt/Jason Lewis/Courteney Cox/the sperm donor of the twins she was expecting … and it’s never true.

I think that engagement rumors are the natural follow-up to pregnancy rumors.  Of course, Penelope is denying all the baby rumors and I’ve posted a picture taken of her on September 11th so you can all see how totally and completely not pregnant she is.  Ahem.

It was only August when Cruz was saying that she wasn’t sure that she believed in marriage, which could be a quote she threw out to throw the media off her track.

In conclusion, it’s way too taxing to try and figure out what’s true and what’s false with these two.  I highly suspect that there could be a head crowning out of Penelope Cruz’s snatch and we’ll still be hearing that there’s “no truth to that rumor”.

Before you caption this or any of the gallery pictures of Mischa Barton roaming the streets of New York City yesterday, I’d like to remind you that Misch, double-fisting her Starbucks, just last week defined herself as a “fashion icon”.  I will send out props for her ability to have a perfectly heart-shaped tear in her t-shirt — obviously a cast-off of Lindsay’s Ungaro collection.
