Yesterday, we reported Britney Spears' upcoming self-arranged photo shoot and tell-all interview with OK! Magazine. Today, TMZ says that the meeting was an unmitigated disaster.

The photos are supposedly so bad, OK! execs say, that the magazine is not sure whether to report what actually happened - or sanitize the truth to protect the train wreck.

According to multiple sources, Britney Spears' behavior during the photo shoot and interview was "nothing less than a meltdown."

She was, according to sources, "completely out of it" during the shoot. The photos are "so bad" that to publish them may "kill her career."

Apparently, Britney Spears' eyes rolled back in her head at one point, causing her to look half dead. Spears' mood, meanwhile, was extremely erratic throughout.

Britney frequently stopped the interview to take bathroom breaks, and each time she returned, her mood would change drastically.

She was also disturbingly paranoid throughout the OK! Magazine interview, fearing at one point - seriously - that the ceiling was about to cave in on her.

Britney sounds about as with it as Lindsay Lohan these days.

We've also learned that the mom of Jayden James Federline had some issues with hygiene on the set as well. At one point, Brit ordered up some fried chicken to munch on. After she chowed down, she wiped her hands on a Gucci dress - worth several thousand dollars - she wore for the shoot, staining it with grease.

One of her dogs (possibly her new Terrier that the Humane Society is fired up about) also needed some assistance... in the housebreaking department.

The dog pooped all over the floor, and Britney used - what else - a Chanel dress to clean it up! This, folks, is white trash behavior even Kevin Federline would scoff at.

As for how Britney Spears looked for the photos? That's another nightmare.

Apparently OK! hired two top L.A. hair and makeup artists to transform the once-bald beauty into something more presentable, but she wasn't havin' none of that.

She refused to let the hired help touch her, opting instead for her "skanky friends" (Lucy Walsh? Alli Sims?) to do her hair and makeup. No wonder she looks so hot!!

If you're wondering where her mom or publicist or lawyer or friend or frickin' ANYONE was to help her out, TMZ says that even her cousin, Alli (who until recently was working as her personal assistant), couldn't deal, and is "done" with Britney Spears.

We'll see when OK! hits the stands this week - if they actually have the cojones to print what really happened. Odds are slightly less than Barry Bonds receiving applause from Kimberly Bell when he breaks the home run record this year.
