Going on no sleep for almost 60 hours seems quite unhealthy for someone in a fragile emotional state, but it’s just another day in the life of Britney Spears.

The walking zombie headed to Studio City, CA this afternoon for a lunch date at Jerry’s Famous Deli.

Donning a Brad Pitt-inspired newsboy cap, Adnan Ghalib was waiting eagerly at the restaurant for his sleep-deprived girlfriend, who seemed dazed and confused from her marathon night Tuesday. Britney was dressed in the same outfit that she had been wearing last night and appeared bedraggled and crabby. The two sped off back to her house in Brit’s new Mercedes before heading to the Beverly Hills Hotel.

For her own mental and physical health, let’s hope Britney calls it a night and gets some rest.

A demure-looking Katie Holmes leaves Joan’s on Third cafe in West Hollywood on Wednesday after lunching there for 90 minutes.

“Katie was enjoying a chicken Caesar salad and iced tea at her table, chatting with other women who passed by to say hello and ask about Suri,” an eyewitness says. “She was having a lot of fun, telling them, ‘Oh, Suri’s fine, thank you!’”

By the looks on Katie’s face, the fun ended when Katie returned to her chauffer-driven Ford Expedition, and the drive back home.

Avril Lavigne shows off her breast stroke (ok, bad joke) as she enjoys Day Two of her week-long vacay in sunny Miami on Wednesday.

The punky popstress was spotted frolicking with her hubby Deryck Whibley (that’s his skinny furball leg) in the hotel pool, wearing a bikini as hot as the weather.

Meanwhile, Avril wants to reportedly trademark her name in connection with a variety of bath products, igniting speculation that a fragrance line could be on the way.

She filed documents last month with the United States Patent and Trademark Office requesting exclusive rights to her own name when it comes to products including fragrances, aftershave, bath soap, body lotion and talc.

While in the midst of her Save the Whales! campaign, Heroes hottie-cum-dogooder Hayden Panettiere manages to find some time to catch up on some reading while waiting for her train in Silver Spring, MD on Wednesday.

With her trusty Harry Potter and the Deathly Hallows book in one hand and her vanilla soy latte in the other, the 19-year-old actress was on her way to the Discovery Channel headquarters to lecture about — you guessed it!! — the strife of whales worldwide.

Clad in all black with stylish matching gloves, Victoria Beckham stops in to meet her fans and promote her denim line DVB inside Saks Fifth Avenue in Boston, MA on Wednesday.

The fashionista/singer is also in town with the rest of her fellow Spice Girls to play a one-off show at the Fleet Center as part of their newly added US tour dates.

Meanwhile, Posh’s way-too-good-for-her hubby David Beckham in Brazil preparing to promote the first David Beckham World of Sport.

A British Britney Spears was up to her usual with Sam Lutfi in the in the midst of her family allegedly trying to stage an intervention.

She kicked off the night by checking into The Beverly Hills Hotel, emerging approximately two hours later at midnight donning a familiar pink wig and making her way to the local Rite Aid. There, she made a number of purchases including the laxative Correctol.

As the sun began to creep on the horizon, she made a pit stop at a Malibu gas station where she bought a mega case of Red Bull, and promptly began to down one upon returning to the passenger seat of her car. By the time Spears made her way back to her Beverly Hills home the sun was bright in the sky and Britney seemed to be in a fighting mood, yelling and cursing at Sam to let her drive.

It seems the mixture of Red Bull, laxatives and lack of sleep have caused her mood swings to continue, which can only be expected considering how high her heart rate must be!

Rosie O’Donnell was so touched by Monday night’s episode of Intervention – “So sad!” — featuring Tressa, a lesbian shot-putter who turned to cocaine and crystal meth, that the celebrity blogger says in a new post she’s giving Tressa a Rosie Family Cruise for four.

Ro invited the rebabilitating athlete and three other pals to come along on the next trip, leaving from New York in July.

All aboard the Rosie gravy boat!!!

Expectant starlet Jessica Alba dropped by the New York City set of The Tyra Show today to cash in on some free celebrity baby shower gifts.

Tyra presented Jessica with a stage full of presents worth over $6000!

As for any changes the mum-to-be is experiencing, Alba tells the always hard-hitting Tyra: “I’ve never dealt with cleavage before… it’s a whole new thing. I’ve increased from a 32B to a 34D.”

Grey’s Anatomy beauty Katherine Heigl clearly still hasn’t managed to give up her nicotine habit as she pops in and out of the swanky Katsuya restaurant in Los Angeles on Tuesday night for a few cigarettes.

The film and TV actress was dining out with husband Josh Kelley (not pictured), who celebrates his 28th birthday on January 30.

Meanwhile, the 27 Dresses actress and her man have been busy with the task of furnishing their newly reovated home.

Katherine has been one of the most outspoken actors when it comes to supporting the writers with the WGA strike, but there is no denying the fact that the 29-year-old actress is enjoying her time off the set!

She may be acting all crazy, but don’t think for one second that bipolar Britney Spears is not seeking medical attention for her condition.

Here the latest from TMZ:

- Brit is seeing multiple doctors, including a new psychiatrist who visits daily and has prescribed her meds (which she’s taking) for her bipolarity

- Certain sources say Britney takes her medicine when she is like “a different person — normal and sweet.” After popping the proper pills for a while, Brit stops her meds because she feels she can live without with

- A “professional” adds: “She’s really trying. Whether it works — we’ll have to see. She has a disease. Sometimes when you see her she’s in the middle of an episode. It’s like mocking someone with Down Syndrome.”

We’re getting sick and tired of Britney and all of her late night bipolar antics. We say, submit her to a lobotomy and let’s get this thing over with once and for all!!
