Britney's Tour Hiccup Over Tots and More

here could be trouble brewing for Britney Spears' endlessly touted "Circus" tour, which kicks off March 3 in New Orleans. TMZ.com reports the popster intends to ditch the so-called comeback tour if ex-husband Kevin Federline's attorneys refuse to allow her to take along sons Sean Preston, 3, and Jayden James, 2. It seems Brit and her decision-making dad, Jamie, who last week obtained a restraining order against shady former hangers-on Sam Lutfi and Adnan Ghalib, have been negotiating the logistics with custody-retaining K-Fed, with the agreement involving setting up three "home bases" in New Jersey, New Orleans and Los Angeles. The tots would stay put at one of those locales while Spears commutes back and forth from her concert dates in each region, which seems like a pretty big commitment for someone who once had trouble even making it to custody hearings. Federline, who reportedly got into a screaming match with a "hysterical" Spears last week over the time the boys have been spending with his new gal pal Victoria Prince, would get his own temporary digs in each city, along with $4,000 a week for his trouble. The problem -- OK, one of the problems with this seemingly misguided plan -- is that it was hammered out sans Federline's pit bull attorney Mark Vincent Kaplan, who is said to be dissatisfied with the terms of the arrangement. He tells TMZ that while he and Kevin have no wish to "interfere" with Britney's career, the plan might have been better received if Jamie and the rest of Spears' handlers had "manned up" and K-Fed had consulted with his lawyers from the start. Kaplan says he's reworking the wording of deal but expects it'll be resolved. So, it seems, does Spears, judging by an item posted Monday on her blog: "Britney is so excited to kick off her tour. ... Both Sean Preston and Jayden James will, in fact, be joining Britney throughout the duration of her tour."

In other dysfunctional pop star news, Amy Winehouse may have reached a whole new level of self-actualization on her extended Caribbean vacation by realizing that she's completely incapable of taking care of her nest egg. The London Daily Mirror reports the substance-susceptible singer has given control of her $20 million-plus estate to her parents, which means she can no longer fork over any cash without their consent. "Everyone is pleased because it means Amy is listening to good advice," a mole tells the paper. "It's still her money and nobody else can touch it. But this stops her doing anything stupid. And it is evidence that Amy is really turning her life around."

Pamela Anderson may realize just how rough she's been looking lately. The Tampa Tribune reports the veteran bombshell channeled her inner diva as hostess of the "Athletes and Angels" pre-Super Bowl party Saturday night, demanding that all the white camera lights be removed from the red carpet. As Pam camped out in her limo, her minions allegedly explained that she must be lit with only "reddish, warm" tones. Once the bulbs were swapped out with the more flattering shade, Anderson made her entrance but left camera crews grumbling over how little time she spent on the red carpet. Perhaps she just needed to take care of business. According to the paper, she caused a commotion when she made a trip to the ladies room and bypassed the dozen or so women waiting in line in her haste to use the facilities.

The CW isn't known for paying the big bucks to its stars, but did cast members from one of the network's more successful shows do an accidental drink and dash? So claims the New York Post, which says "Gossip Girl" co-stars Chace Crawford, Leighton Meester and rumored off-screen squeezes Ed Westwick and Jessica Szohr forgot to settle their bill after an "impromptu party" in a private room of a Manhattan bar last Thursday following the Kings of Leon concert at Madison Square Garden. Seems that when the evening ended in the wee hours of the morning, "Nobody ever paid the $500 bar tab the group racked up."

BEYONCE : Single Ladies On a big Hit on Top

Beyonce has finally infiltrated my house. My kids and my wife are all singing "Single Ladies (Put a Ring on It)." Nonstop. Every day. It's the answer to every question and the response to every statement. It's worse than waterboarding. I'd leave, but I know they'd follow me.

There are songs you wish you could forget but can't. They're like a virus that won't leave your system no matter how hard you try. You're in the shower, and before you can stop yourself "Y.M.C.A." pops out of your mouth. You catch yourself chanting, "Who let the dogs out?" in the car. You respond to a friend's recent troubles with "I get knocked down but get up again."

You try to erase these unwelcome melodies by thinking about something else. Nothing. You sing them ten times really loud and fast, hoping to push them out of your head. No luck. They won't leave you. You're afraid to go out at night. You used to be so much cooler than this.

Go easy on yourself. You're not to blame. There's a name for the affliction, and it's called "brain itch." And the type of song that causes the brain itch? That's an "earworm." Dr James Kellaris of the University of Cincinnati has studied the phenomenon (for real). It seems the combination of repetitive words and unchanging melody makes for the perfect earworm. We're helpless against its power.

Here are the all-time itchiest of the brain-itch tunes. You can rest easy knowing that it's not really you singing that song. It's that earworm dug into your mind, like in the movie "Scanners." At least now no one can blame you when your friends ask what you want for lunch and you say, "I want my baby back, baby back."
