Nicole Richie's heading to Britney Spears's concert in Los Angeles tonight and she's pumped.

Richie uploaded a video of her and a friend getting down to the Brit classic "I'm A Slave 4 U," tweeting "In honor of my queen, @BritneySpears - Can't wait to dance tonight!" We must say, Richie's not bad!

Paris Hilton has split from the Vegas club owner after about a year of dating, according to Us Weekly.

"They are broken up," said a Hilton pal who apparently speaks with pronounced inflection. "It's sad, she cares about him a lot and thinks he's a great guy but they really hit a rough patch."

As for the reason behind their break-up, the source said, "[Cy's] found it difficult to live his life with her in the spotlight and that's what caused their split. No drama, it's amicable, but things didn't work out."

It took him a year to realize that dating Paris Hilton meant a "life in the spotlight"? We would more likely believe that Hilton ended it after having a dream they should break-up or because she didn't like a pair of shorts he was wearing.

Tragic news: "Jackass" star Ryan Dunn and an unidentified passenger were killed in a fiery car crash in the Philly suburbs this morning. Police said Dunn's 2007 Porsche 911 GT3 was "off the road and in the woods," engulfed in flames after apparently careening over a guardrail. The 34-year-old daredevil may have been speeding, reports the Associated Press. 

A jaw-dropping photo of the wreckage was posted on Twitter -- then deleted. Someone swiftly uploaded the image on Flickr. Another sad reminder of the fleetingness of life: just hours before his death, Dunn tweeted a photo of himself and some friends drinking and hanging out, without a care in the world.

Dunn, a long-time member of Johnny Knoxville's merry band of prankster-stuntmen, made appearances on MTV's "Jackass" and "Viva La Bam," and also had his own MTV series "Homewrecker." He met "Jackass" castmate Bam Margera in high school, and had been working as a welder and at a gas station when his extreme skateboarding-and-stunt

File under "Inappropriate Things" and "Ew, Gross!": actor Doug Hutchison, who is 51 years old, has married wannabe country singer Courtney Alexis Stodden, who is 16. Yes, SIXTEEN. A child bride.

Who does Hutchison think he is, R. Kelly? Jerry Lee Lewis, who wed his 13-year-old cousin?! All right, Hutchison and Stodden are not related (as far as we know), but Stodden is still neither old enough to vote nor drink alcohol, among other adult rites of passage; just three years ago, she was a tween. A TWEEN.

The happy couple got hitched in Vegas on May 20, and they insist they're the real deal. 

"We're aware that our vast age difference is extremely controversial," quoth the newlyweds, via their publicist. "But we're very much in love and want to get the message out there that true love can be ageless."

Hutchison's acting credits include "The Green Mile," "I Am Sam" and ABC's "Lost," on which he played the Dharma Initiative leader Horace Goodspeed. Here is a picture of Horace with really

"Oops. Busted by New Yorks finest." - Getty ImagesGwyneth Paltrow is probably the last celebrity you'd expect to get into trouble with the law, but Queen GOOP herself apparently had a run-in with the NYPD Friday night.

Paltrow posted a picture on her Twitter account of the cops approaching in her rear-view mirror.

"Oops. Busted by New Yorks finest," she wrote.

Any guesses as to why Paltrow was being pulled over? Maybe her luminous glow was blinding fellow drivers? Maybe the cops heard her singing and decided that warranted a citation? Maybe they just wanted a recommendation for organic, veggies-only, gluten-free dining in the city?

Somewhere, Tiffani Thiessen is smiling. - George Pimentel/WireImageThat Justin Bieber, always keeping us guessing. The 17-year-old pop titan showed up last night to the MuchMusic Video Awards in Toronto sporting a Kelly Kapowski t-shirt. We have to give him props for his taste, especially considering that when Bieber was born in 1994, "Saved By The Bell" was already off the air.

Bieber's girlfriend Selena Gomez -- who arrived with an unfortunate curls situation -- hosted the show, which meant that when Bieber came up to accept an award for Best International Video by a Canadian, this cringe-worthy exchange happened between the real-life couple.

When Pippa Middleton walked into Westminster Abbey in her curve-hugging bridesmaid dress, she stole thunder from A) J.Lo's butt and B) her own sister, Kate, on her WEDDING DAY. And now she's a breakout tabloid star whose love life is far more interesting than what Kate and William wore to whatever stuffy polo match. That's what Mindy Kaling calls getting "Pippa'd." The star of "The Office" puts the phrase in context:

Excellent usage. - Mindy Kaling/Twitter

The lesson here is to never cast Angelina in a supporting role in your film -- she will undoubtedly outshine you, win an Oscar for the role, then maybe steal your man. And never let your hot sister carry your bridal train wearing a sexier white gown, thereby diverting the world's attention from you to her ample derriere. Although, given the newly minted Duchess' selection of scene-stealing bridesmaids, she got Pippa'd by others beyond her celebrity sibling. 

Lamar, Khloe, Kim, Kris. - Denise Truscello/WireImageIt was a busy weekend in Kardashian Land (a land where every word starts with "K" and no problem can't be solved with a credit card).

On Thursday night, Khloe -- who knows a thing or two about weddings-on-short-notice -- threw a last-minute engagement party for Kim. Khloe called on Sharon Sachs, the same wedding planner she used for her wedding to Lamar Odom in 2009.

"She did my wedding in nine days, so I was like, 'You can put together an engagement party in three days!'" Khloe said. "It was really fun."

About 50 or so people attended the party, many of whom had not even met Kim's New Jersey Nets fiance yet.

Then, Friday night, Khloe and Lamar and Kim and Kris jetted to Vegas to celebrate Khloe's 27th birthday with a dinner that sounds like it would have been perfect for a 8-year-old's birthday (fried macaroni and cheese balls, milkshakes, etc.)

They then made their way to an exclusive VIP room where "both couples were seen glued to each others' side all night, and they danced until
