Britney Spears

Rihanna and Britney Spears are set to collaborate on a new song.

That song is believed to be a remix of the former's hit, "S&M".

Rihanna announced it first, writing this on Twitter: "I got a sexy collaboration coming your way super-dupa soon! By popular demand... it's Britney bitch!"

Spears' manager replied: "Rihanna you're such a tease! I like it, like it..."

This duet will be off the chain ... see what we did there!?

Rihanna tweeted last week asking fans whether they would like to see her rework the song with another pop star, and if so, who. Britney seems like a great fit.

They've got their work cut out to top the original video, though:

Is Britney Spears ready to become a bride once more?

As she enjoys mammoth sales and the strongest reviews of her career for seventh studio album Femme Fatale, will she settle down for good with Jason Trawick?

"Maybe someday," she teases. "Never say never!"

Not a glowing quote, but she adds: "We have such a great time together! He makes me laugh, and are so comfortable being ourselves. I've never been happier!"

She may not be engaged yet, but don't count it out!

A family source says that the blissful pair will likely wed down the road, as Jason Trawick "was one of the only people who stuck by her through everything."

In 2007 and early 2008, Spears lost custody of her sons Sean, 5, and Jayden, 4, to ex Kevin Federline, and was briefly admitted to a psychiatric hospital.

Trawick, then her agent and now her boyfriend of two years, never wavered.

"[Jason] was someone she felt she could be her true self with. [Marriage] is what they talk about and the direction they're going in," the insider says.

Spears, who just released her new "Till The World Ends" video, does look so much healthier these days, don't you think? We're glad she's happy.

Britney Spears is going apocalyptic in her new music video.

It's Dec. 21, 2012. The sky is falling. But Britney Spears just wants to dance ... "Till The World Ends." It's a noble endeavor, and she sure gives it her all!

The pop star is the center of attention in an underground, futuristic club, where as asteroids threaten to destroy the city above. Brit remains undeterred.

Her "Slave 4 U" video certainly comes to mind with the imagery and outfits donned by Spears. Watch it below and leave a comment with your thoughts:

Britney Spears - Till The World Ends (Official Music Video)

Britney Spears' music video for "Till The World Ends" doesn't drop until tomorrow, but the Spears Marketing Machine leaked a 30-second teaser to hold us over.

The second single from Femme Fatale, following "Hold It Against Me," "Till The World Ends" has been heralded by many Spears fans as her best track in years.

It's waaay better than HIAM, in THG's opinion. We can only hope the video measures up to the song, a thoroughly catchy Britney hit. Here's the video tease:

Britney Spears - Till The World Ends Video Teaser

Pop phenomenon Ke$ha wants to skinny dip with Britney Spears.

Sounds awesome, save for the part about Ke$ha being there.

That topic came up when the dollar-signed singer was asked how she would like to celebrate the success of her chart-topping "Blow" and "Till the World Ends," Spears' latest single that Ke$ha actually wrote. "Skinny dipping," she said.

"Either her place or my place, it doesn't matter."

She recently put in an underwater stereo in her pool in Nashville, too. Convenient.

Who would you rather skinny dip with?

Britney Spears is pregnant for a third time.

So Life & Style would have you believe, anyway. We'd chalk this up to a giant April Fool's hoax, but L&S reports such things every other week.

No way is Britney Spears pregnant. She's just now emerging from an 18-month hiatus, performing and mixing cocktails with the best of 'em.

She's also not married to Jason Trawick, and has her hands full with Sean and Jayden. No way she's having another kid while unmarried.

More like non-baby drama. One lie and two non-stories! Crazy!

Britney's made some mistakes in her past, yes, but she's pulled it together well now, and is so micromanaged that there's simply no way this is true. None.

At least the Kim Zolciak-NeNe Leakes portion of this magazine expose is more or less accurate. Not interesting to say the least, but more or less accurate.

From touring with Lil Wayne to opening for Britney Spears?

It could happen for Nicki Minaj. Britney has reportedly honed in on as her opening act for her Femme Fatale tour, with lawyers for the two in "serious talks."

Sources say it looks very promising that Nicki and Britney will reach an agreement in the next day or so. Think that would be a promising concert tandem?

SPEARAJ: Britney and Nicki may team up this summer.

Nicki would fill the void left when Enrique Iglesias bailed at the last minute because his ego could not take being an opening act for Britney Spears.

Minaj is currently on tour with Lil Wayne, however those concerts end on April 28. Britney's tour begins June 17 in Sacramento, so it could work.

If it goes down, you'll be the first to know when we do.

In music and in fashion, Britney Spears is back on top.

She’s not renowned for stepping out in high-fashion threads (she prefers the hooded sweatshirt and jeans look, y'all), but she sure looks the part if she tries.

Case in point? Sexy ensembles from Italian designers Dolce & Gabbana in a new set of promotional ads for the company. See Britney Spears pictures below:

“We love Britney Spears and we love to dance to her new songs! We can’t wait to hear the whole album,” the design duo told the Telegraph (UK).

“She has always been among our favourite artists because she has been able to remain true to herself and to her style throughout the years."

"With her music she influenced and inspired generations of people for more than 10 years, and we can’t but congratulate her for this achievement.”

Indeed. She looks a little confused in the first image above, but that's pretty much par for the course these days. Confused but oh-so-sensual.

Britney Spears is being sued by her former business partners for breach of contract, fraud and deceit, and it all stems from her signature scent.

The pop singer was slapped with a $10 million lawsuit because of Radiance and a multi-million branding deal with beauty giant Elizabeth Arden.

Britney and father Jamie are accused of being "sneaky and underhanded" in moves to cut Brand Sense Partner, LLC., out of a licensing pact.

Another week, another legal saga for Britney Spears.

"Britney secretly made a deal with Elizabeth Arden in an underhanded effort to circumvent and evade obligations to Brand Sense," the suit states.

"Effectively, Britney improperly and illegally cut Brand Sense out of the deal." Brand Sense accuses Britney of "concealment and evasive actions."

We have no idea who's in the right and who's in the wrong here, but we strongly suggest she name her next scent Poo Cocktail. So seductive.

Britney Spears appeared on Jimmy Kimmel Live last night, and on top of performing two tracks from her new album, showed us how to make a very special cocktail.

This was, in fact (not really), a deleted scene from Jackass 3D. It may not have made the final cut, but Johnny Knoxville was kind enough to share it with us here.

It's called Poo Cocktail Supreme. Britney Spears is the "bartender" of sorts. If you get queasy easily, you might not want to watch this. Everyone else, go to it:

Britney Spears and Johnny Knoxville

Mmm. Delicious. Makes you look forward to happy hour even more.

Follow the jump for Britney Spears performing "Till the World Ends" and "Hold It Against Me" on JKL. The latter performance was cut off as the credits rolled.

Kimmel Tweeted: “To all experiencing fits of intense hissy because the @britneyspears bonus song was short, not our decision if it airs online – artist mgmt.”

That explains it ... sort of. Check out both performances here:
