Is she? Or isn't she? Is she? Isn't? Is? IsIsn't?

Britney Spears always made my head swim with confusion, doubt, and thoughts of suicide. (She's a lot like proto-existentialist Søren Kierkegaard that way.)

In the latest Brit mind-puzzle, there are conflicting reports about the state of the two-time divorcée's love life. Is the former Mrs. Federline dating her agent, Jason Trawick? Are they engaged?

In an elegant report (to wit: "secret all-nighters!"), Us Weekly claims they share the same hotel room when traveling. (It sure saves money.) What's more, a "source" tells Us that "[Brit's da] Jamie loves" Jason and that "Jason totally drinks Jamie's Kool-Aid." (Switch to fresh fruit.)

Star mag claims J.T. has popped the question, even though "he didn't exactly get down on one knee."

Access Hollywood says the report is bogus, while an "insider" tells OK! that J.T. hangs around Brit only to protect his financial - not lurv - investment.

Is there life after Chris Brown?

Is romance even possible after

Chris Brown

?

In an Exclusive! Report!, Hollyscoop.com claims Brown's ex-gf, Rihanna, who was allegedly assaulted by the smooth R&B man, has finally moved on - and into the arms of Canadian actor-singer Aubrey Drake Graham. A.D.G. has been hyped as the new Fresh Prince. (I'm sure Will Smith loves that comparison.)

Proof?

The pair were "attached at the hip" at a New York party Wednesday night, says Hollyscoop.

Is there life after Samantha Ronson?

Apparently not.

Lindsay Lohan, who reportedly reconciled with Samantha Ronson after being dumped by that heartless - albeit totally lovable - DJ, has been ditched again.

Or has she?

Citing an anon source, People mag says the couple never got back together, but tried reconnecting only as friends, an experiment that has failed. "Sam let Lindsay back into her life as a friend, but now even a friendship seems impossible," says the source. "No matter how many times she promises to change, Lindsay loses control and starts acting like a maniac."

Sadly, it seems, LiLo is "telling everyone that Sam dumped her again."

Mum: Amy Winehouse needs saving

In an interview broadcast yesterday by Britain's ITV News,

Amy Winehouse

's mother says the troubled singer desperately needs to be rescued.

"Amy is in denial all the time" and is mired in a never-ending cycle of drug addiction, says Janis Winehouse. Amy's father, Mitch, says the soul singer continues to drink even though she is on a drug-replacement program.

LiLo and the case of the missing jewels

Meanwhile, Scotland Yard is investigating the disappearance of over $400,000 worth of Dior jewels from a

Lindsay Lohan

photo shoot, and they want to talk to her about it.

Harry Potter does not plagiarize . . .

Probably because he's not real, but fictional.

But has his creator, J.K. Rowling, resorted to plagiarism? Rowling's publisher, Bloomsbury Publishing, is rejecting a copyright lawsuit by the estate of nonfamous, non-mega-selling deceased British fantasy writer Adrian Jacobs, who claims that Rowling plagiarized from his 1987 book, The Adventures of Willy the Wizard: No. 1 Livid Land in the fourth book in her Potter series, Harry Potter and the Goblet of Fire. Filed in 2004, the suit is finally making the rounds of London's High Court.

Knight's tale: Closure?

At last, it's over! (Or is it?)

In the 8,907th report claiming to be the last word on the affair, Entertainment Weekly cites an anon source who confirms that "ABC has granted T.R. Knight's wish to be released from his [Grey's Anatomy] contract." So, wait, if he's released, does that mean he'll be back on the show or he's left the show?

LiLo's Twitter snafu

Lindsay Lohan

(that woman

again

) denies that she Twittered that she had witnessed her special ex-Mouseketeer

Justin Timberlake

cheat on his current gf

Jessica Biel

.

"I would not discuss my personal life, let alone someone else's, on the Internet!" LiLo tells Life & Style Weekly. But the actress confirms the post was made on her actual Twitter page, implying that it was posted by a hacker.

"Twitter needs to fix their [stuff]," she says.
