Ladies and gentlemen, Justin Timberlake is dating. Yes, that’s right, he’s dating. There is more than one woman in whom he is interested, and so he is spending time romantically with both of them. You’d think the media would be familiar with this concept, as they all watch Grey’s Anatomy, and Meredith laid the concept out pretty clearly a couple months back, but everyone still seems shocked. It’s not a committed relationship … but it’s not cheating … how do we frame this?

After frollicking around Sundance with Jessica Biel, JT was back in the arms of Scarlett Johansson in Miami. The two were spotted at a Super Bowl afterparty, where, according to witnesses, “they were talking, dancing, holding hands all night - it was very cozy. Then, as they left through the back, Justin was leaning against the wall and Scarlett came up, leaned into him and did a sexy, little dance, grinding into his body.”

I am really, really happy about this, mostly because Jessica Biel is certain to be really, really unhappy about this. I take great pleasure in the little things.

I hate both the MPAA and the FCC. Essentially I hate censorship in all its forms and I advocate a society where I’m allowed to choose what I’d like to guzzle.

That said, I am a little confused by this news: Justin Timberlake will be hosting the Kid’s Choice Awards. I know what you’re thinking, “Hey, what the hell are the Kid’s Choice Awards?” Fair point.

But I bet they involve children, unless it’s some kind of weird pedophile buffet thing. In which case I bet getting sponsorship/televised would be a bitch. So JT and the kids getting together because he’s a kid-like role model style guy. I now present you some selected lyrics to “Sexy Back.”

Dirty babe
You see these shackles
Baby I’m your slave
I’ll let you whip me if I misbehave

Oh crap, I appear to have misspoken. Later on in the song it says:

Go ahead child
Go ahead, be gone with it
And get your sexy on
Go ahead, be gone with it

Now I understand, the kids are meant to be sexy and also objects of sex. Dios Mios man. Was Guarini not available?

Take it to the bridge!

Justin Timberlake’s only been single a matter of weeks, and the classy and talented Jessica Biel has already made herself available to him for whatever it is he may need companionship for — snowboarding, dining, what have you. Biel made a special trip to Sundance, where she is not promoting a film, to spend time with Justin, who appeared in “bad Ricci-porn” Black Snake Moan on Wednesday.

According to Perez Hilton’s source, “Jessica was picked up in her chauffeur-driven Volkswagen Touareg car and instantly went to visit Timberlake when she got into Park City,” which begs the obvious question: why hasn’t Volkswagen’s PR team contacted me for a plug? The two spent time together snowboarding on Thursday and probably also doing any number of things I can’t write about here.

Biel, who recently split from baseballer Derek Jeter, was spotted backstage at a Timberlake concert earlier this month, and was rumored to be the cause of a Cameron/Justin blow-out at the Golden Globes.

Blech! Justin! If you want us to take you seriously as an actor, maybe you should stop hanging out with someone who read the script for Stealth and thought, “Here’s a can’t-miss premise.” Next thing you know, you’ll be starring in bad Ricci-porn!

PS — Check out the JT magazine cover in this old-school Jessica photo!

Check out these adorable pics of Cameron Diaz — still in Hawaii — with buddy/love interest(?) pro surfer Kelly Slater. It’s good to see her happy again. But this isn’t going to stop Us Magazine from releasing new deets about her Golden Globes war with Justin:

“Cameron was across the room giving them the evil eye,” says a party source. “It was like high school.”

Another witness says that pal Drew Barrymore even attempted to distract Diaz from her ex’s hookup-in-progress with Biel, “grabbing Cameron to dance, trying to make her have fun.”

What Diaz did next, barely five days after announcing an amicable split with Timberlake, her boyfriend of nearly four years, shocked the whole room.

“All of a sudden she just lost it,” says one of the many witnesses to the tantrum of Diaz. “She came up and started yelling at Jessica.”

According to a witness, Biel, 24, stepped away, leaving Diaz, 34, to unleash her fury on Timberlake, 25, who moved with her into a hallway.

Says a guest, “First she started saying all these nasty things to him about Jessica like, ‘What is she? Your new f—king girlfriend? Look at her!’ And then she insinuated things about other guys that Jessica has been with.”

The tirade went on for 45 minutes, until Barrymore finally intervened. Says a source, “Drew had to grab Cameron and say, ‘It’s enough.’”

I can’t say I blame her. Jessica Biel’s kind of a dirty slut. But I do wish I had her ass. Whatever, it doesn’t sound like Justin hit that anyway. Good lookin’ out, JT!

Things have not been going well for Cameron Diaz lately. For starters, she and longtime boyfriend Justin Timberlake split early this month. When Justin left, he apparently took with him all of Cameron’s ability to choose dresses and hair colors, as she’s looked like hell since. Her People’s Choice dress looked like it might eat her, and her Golden Globes ensemble gave Bjork’s swanfit a run for its money. So it shouldn’t come as a surprise that Cam totally lost her cool at a Globes after-party when she saw JT chatting up Jessica Biel (whose relationship with baseball star Derek Jeter is rumored to be “open.”

According to Page Six,

Sources say the temperamental star “blew up” at Biel after she saw Timberlake flirting with her. Diaz followed Timberlake to the In Style party at the Hilton Oasis, where “they had an awkward conversation.” The “Charlie’s Angels” star then trailed Timberlake to the Beverly Hilton rooftop for the Universal party, where she found him chatting up Biel - and screamed at the “Illusionist” star. “If that’s how she wants to get him back, it won’t work,” said our insider. “She’s desperate.”

Looks like it’s going to be interesting to have these two back on the singles scene.
