The National Enquirer claims in a new cover story that Britney Spears was sexually attacked by someone who knew her in mid February, which prompted her to shave her head and spiral downwards. She is off her meds, talking in strange voices, and refuses to wear clothes in the house, they say.

Their mention of Britney’s attack is vague, and could be entirely based on a rumor that originated on popular aggregate celebrity news site Oh No They Didn’t.

Here’s how The Enquirer explains the incident:

Despite months of hard partying and substance abuse that ultimately landed her in rehab, The Enquirer has learned that Britney’s downward decline accelerated in mid-February when she was attacked in Miami by someone she knew who wanted to have sex with her.

Although her rep denies this incident took place, sources say she hasn’t been the same since.

Just three days after the assault, Britney… [shaved] her head.

We reported this rape rumor back in mid February. Supposedly Britney went into Cedars Sinai Medical Center, which is in LA, not Miami, after she shaved her head, and was there for unknown reasons. (Not a toothache.) Britney was in Miami alone with her two children in mid February, and she did leave earlier than planned. She originally planned to spend a full week at the Four Seasons resort there with her kids, but left after just a few days. As we reported at the time, a source told Us Weekly that “something happened” that made her want to hightail it out of there.

It could be that The Enquirer received confirmation of this attack, or that they’re connecting the dots based on conjecture and already-known facts about Britney.

The rest of the story focuses on the leaked flower boob pictures, and the weird video rant Britney gave to X17 in which she sarchastically said the world is so nice and talked about how her manager totally knew what he was doing by sending her go to rehab. She’s off her medication, they say, and is having mood swings and blaming everyone else for her breakdown.

We already knew this about Britney, but the part I found interesting is the fact that she plans to make sure her father, who spoke out in support of her ex-manager, Larry Rudolph, is not going to see a dime of her future earnings.

Her ex, K-Fed, is also said to think she’s got a split personality and not to trust her:

She’s currently in the process of trying to negotiate an end to her contract with Rudolph – which she only recently signed. And sources say that Britney will also cut off some of her family members financially, including her father Jamie, who has recently gone public with criticism of her conduct…

“Kevin feels like he’s been watching someone with a split personality,” said the source.

“Kevin said he feels like he is talking to different people when he speaks to her.

“One minute Britney is fine, and the next she is blowing up at him and the rest of the world. She’ll tell Kevin she is moving out of L.A. and quitting the business, and then in the next sentence say she is going on tour soon, so he better get his act together so he will be able to keep the kids full time.”

Britney may be whacked out of her mind, but she’s still able to lipsynch and gyrate for 10-15 minutes at a time. She performed at the Las Vegas House of Blues this weekend for more of the same in her “comeback” tour.

Thanks to FlyNet Online for these pictures of Britney in Vegas. Hey she changed her boots! The new ones are just as ugly, but at least she’s wearing sandals with that shirt she seems to think is a dress.
