The ad campaign is part of the pop star’s PR blitz accompanying her comeback album "Circus" and supporting tour.

"I had so much fun," Spears said after the photo shoot. "My favorite set-up was against the gigantic wall of pink cotton candy."

It looks like Spears has finally shed her baby fat and is back in fighting shape.  Or perhaps the editor is just really good with Photoshop.

First Britney Spears dumps slacker husband Kevin Federline by text message. Next, rumors fly that Kevin is shopping around a 4-hour Britney sex tape from their honeymoon.

Then Kevin states publicly that they are getting divorced because Britney is bisexual and was pressuring him to bring other women into their bedroom. And that’s a bad thing because…? Help me out here, I’m a little blind to the downside.

Britney Spears continued her very public liberation from K-Fed by stepping out with celebrity socialite Paris Hilton, resulting in a number of wild paparrazi photos including upskirts of Britney’s private parts (both with and without panties) and this puzzling photo of Paris giving Britney a titty-twister.

Looks like Britney is making good on her bisexual desires. Not that there’s anything wrong with that, especially when she provides photographic evidence! Apparently Paris is the “top” in this relationship.

But Britney, you’re about to enter a nasty divorce contest against a man who has nothing to lose and everything to gain. Do you really think this is a good game plan? Party in private! Just my two cents…

Then K-Fed fires back with a counter-claim seeking spousal support and custody of their kids. Which makes sense because we all know what a great father he is, as he demonstrated by leaving his wife and other children (including one about to be born) for Britney in 2004.

Within days of their divorce announcement, rumors of a four-hour Britney/K-Fed sex tape emerge. Reportedly BetUS.com was negotiating with K-Fed to publish the tape, which is apparently more graphic than the infamous Paris Hilton green sex video and is projected to outsell it by far.

You may recall that in 2005 Britney sued “US Weekly” for a story it ran titled “Brit & Kev: Secret Sex Tape? New parents have a new worry: Racy footage from 2004.” Britney then denied existence of the tape and sued the magazine, ultimately losing because of course the tape is real. These are the same two narcissists who broadcast to millions of people a “Chaotic” home video of themselves burping and farting, so it’s no stretch of the imagination to believe they also have video of themselves doing the nasty.

The latest twist in this story is that Britney may simply give away the sex tape for free, just to spite her soon-to-be ex. “Brit figures she’ll beat that sucker to the punch, just like she did by giving away pictures of Jayden James,” said Spears family friend Nyla Price, 55, the owner of Nyla’s Burger Basket. “Half of nuthin’ is nuthin’, and that’s what her lying skunk of a husband will get if she gives that video away before he can find some sleazeball to buy it.”

We believe there is a sex tape, and as soon as K-Fed realizes he won’t make a dime off it, he’ll pull the plug so the world won’t have to see his sorry a** on film. But after disappointing sex tapes from Pam Anderson and Paris Hilton, all we can say is “Baby, one more time!”

Schelske denied all of the allegations in statement issued Friday night: “I have made the decision to forgive Sara for the unfortunate campaign that she and her publicity advisors are currently waging. Sara has unfortunately become a dramatically different person over the last year and it is something we have struggled to deal with. Sadly, it appears we have failed.”

And therein lies one of the many fundamental flaws in marriage: You are expected to open up and bare your soul to your mate, only to have your mate use your inner demons against you in a court of law. For the sake of their three kids, let’s hope that Evans and Schelske find a way to battle in a more private venue.
