Pierce Brosnan -- The Name is Battery Suspect

TMZ has learned the L.A. County Sheriff's Department is investigating Pierce Brosnan for allegedly battering a man in Malibu.

The incident allegedly occurred outside Casa Escobar last Friday in a Malibu mall about 6:15 PM. We're told Brosnan allegedly committed a battery on Robert Rosen, a photographer.

According to Rosen, Pierce was there with his kids, when Rosen began snapping photos (see below). Rosen says Pierce then said, "Why don't you get a real f**king job." Rosen says he then started complimenting Pierce on his Bond roles.

A short time later, an enraged Pierce allegedly told the photog, "Why don't you f**k off, mate," and then struck him in the ribs. A witness says the pap instinctively reacted by kicking Pierce -- we're told, in the stomach.

Sheriff's spokesperson Steve Whitmore says his department is "actively investigating" the matter and will be referring the case to the L.A. County D.A. for review.

Brosnan's rep was not immediately available for comment.

YOU'VE GOTTA SEE THIS!!!

Britney Spears was pulled over by an L.A. Sheriff last night -- and while she got off with just a warning, the scene around the car was complete insanity.

TMZ caught Spears and ex-assistant/"cousin" Alli Sims leaving Winston's late Monday night, where the two were quickly pulled over for a minor infraction, nothing serious. Brit wasn't driving, but it was her Pumpkinmobile, and Alli can be heard telling the officer, "We'll get one this week, she just got this." It's unclear

what was said, but It appears that Brit's temporary tags might have expired.

After the officer walked away from the vehicle, a drunk guy started shaking his booty against Brit's window, with Spears looking extremely confused (more so than usual) as he kept dancing. A screaming match broke out in front of the car too. Gimme more crazazy!

Bill O'Reilly hasn't been able to get Rosie O'Donnell on his show, so he brought the show to her!

The FOX News host sent a cameraman and a producer to a Long Island book signing O'Donnell was doing this weekend, to ask Rosie why she wouldn't come on his program. She told O'Reilly's people, "If Bill wants me, he should phone me himself. He's a big boy."

But then the conversation turned to 9/11 and how Bill feels that Rosie mangled the truth by claiming it was "an inside job." Rosie responded, "I didn't say that, he's quoting the wrong

people." Someone on TV got something wrong?! Get out!

As the conversation became more heated, one of Rosie's handlers started to shove the camera guy, but Rosie told him not to because, "That's what they want."

The whole incident subsided, and on last night's show, O'Reilly reiterated his invitation for Rosie to appear. He shouldn't hold his breath!

David Copperfield uses his shows to pick up women -- this, according to multiple sources in contact with TMZ.

Here's the way it goes down: For years, David's assistants have targeted attractive women sitting in the audience. During the show, David will bring them up on stage, and if he likes them, he uses code words ("mama" and "secrecy") to let his assistants know he's interested. After the show, the assistants bring the women backstage, where they meet David, have their pictures taken and fill out questionnaires on colognes they like, whether they enjoy the Bahamas (where he owns property), etc.

One woman who David recently targeted gave TMZ a voicemail message that David left shortly after the performance.

Another woman -- Amanda from Atlanta, told a similar story. As did another woman from New York.

None of these women say David did anything untoward, but a Seattle woman reportedly claims David sexually assaulted her in the Bahamas. The Feds are investigating.

Paris Hilton as a sexy Alice in Wonderland and Larry "I am your father" Birkhead as Darth Vader were spotted on Saturday night, partying it up at the Playboy Mansion. Battle of the bottle blondes!

Other guests included Paris' less famous sibling, Nicky, Adrien Grenier, Hugh Hefner and Quentin Tarantino. Clearly, Larry's saber grabbed the heiress' attention. *kssshhhhhhhh phhhhhhhhhssshhkkkhh*
