Kim Kardashian tried to steal the show at the Roc Nation pre-Grammy brunch in Beverly Hills on Saturday, but she had to compete with a smokin' hot Rihanna -- AND Beyonce!

Kim showed off her shorter hair and rocked a revealing red top and skirt combo, and she posted a photo on Instagram of Kanye West's new Yeezus 3 sneakers, which she handed out to guests at the bash. "Yeezy put me in charge of the fam distribution #YeezyBoost #AdidasOriginals #ThisFirstRunIsAsizeTooBig #WifeLife #WifeGotThatWork." At least she did something useful!

Jay Z and Kanye sipped on cocktails and posed for a few photos together, and Beyonce also made the rounds, along with Bad Gal RiRi, who gave both Kim and Bey a run for their money with her sexy Altuzarra getup...

Bruce Jenner was involved in an accident on the Pacific Coast Highway in Malibu yesterday that left one woman dead, and while he passed a field sobriety test, police will be checking to make sure he wasn't texting at the time the fatal crash occurred.

A woman in a white Lexus sedan was coming to a stop at a red light when Bruce rear-ended her in his black Cadillac SUV, at which point she was pushed into oncoming traffic and struck by a black Hummer. Police have determined that Bruce was not speeding, but Los Angeles County Sheriff's Department Lt. John Lecrivain did note that there is no evidence that Bruce was being chased by paparazzi.

Lecrivain added, "There was a possibility that paparazzi was following him at the time of the crash, but that is a very regular occurrence, and (there is) no indication at this time it was a contributing factor of the crash." At the time of the horrific accident, Jenner family sources told TMZ Bruce was being chased by as many as 5 photographers.

Sheriff Commander Michael Parker said investigators are now trying to determine the circumstances surrounding the crash, The L.A. County Sheriff's Department will get a search warrant for both Jenner's phone records and the phone itself. It is illegal to text and drive in California, and a few photographs show Jenner with his hand raised while behind the wheel, so it's not clear whether what he was doing at the time of impact.

Seven victims were taken to the hospital following the crash, and Bruce was escorted to the station in a cruiser, though he was released shortly afterwards.

Bruce Jenner was involved in a car accident around noon on Saturday that left one person dead and several others hurt.

The reality TV star was driving along the Pacific Coast Highway in Malibu, and eyewitnesses tell TMZ that Bruce's black SUV rear-ended a white sedan, which was then pushed into oncoming traffic and struck by a Hummer. The woman driving the white car died, and there were 7 other people involved in the accident, all of whom sustained injuries.

Bruce told police he was not drinking and volunteered to do a field sobriety test, which he reportedly passed. X17 photographers were not on the scene when the fatal crash took place.

There's a reason why her Little Monsters love her so much -- it's because she ALWAYS makes time for them!

Lady Gaga attended the MusicCares bash in downtown Los Angeles on Friday night, and from the crazy makeup to the revealing dress, she went all out for the occasion. The pop star rocked an impressive platinum blonde wig, and she smiled happily as she posed for selfies with her fans.

Tony Bennett accompanied her to the event, and the duo are set to perform at Sunday night's Grammy Awards. Can't wait for that!

Jessica Alba took her daughters Honor and Haven to the Gwen Stefani concert at the Orpheum Theater in downtown Los Angeles on Friday night, but they weren't the only famous faces in the crowd! Kris Jenner and Melanie Griffith carpooled to the show, and though Kris is known for being the sexiest senior in town, Mel definitely one-upped her with a pair of skintight leather pants and a sheer top.

This marks Gwen's first solo show in six years, and last month revealed that it would be part of the MasterCard Priceless Surprise Performance series.

"MasterCard has created a movement that is cutting through the predictability of everyday life to deliver something special to people – something priceless – and I’m excited to be a part of that," Gwen said. "We are working together on some amazing surprises for the L.A. show."

Did on-again girlfriend Katy Perry put him up to this?

John Mayer guest hosted The Late Late Show for three nights this past week, and on Friday he wrapped things up with a monologue that was so awkward it was actually funny.

Mayer plugged the Grammys, which will air Sunday on CBS, and added, "You can see me at the Grammy Awards doing what I do best ... Being avoided by Taylor Swift." Mayer quipped, "that won't make the Internet at all." Sure, but did he come up with this all on his own? We doubt it...

Mayer and Swift briefly dated in 2010, and though the weren't exactly friendly after they split, when Mayer started dating Katy Perry, things seemed to take a turn for the worse. Both Perry and Swift took jabs at one another in interviews and on social media, and when Perry hooked up with DJ Diplo several months ago, he took to Twitter to post a number of nasty things about Swift. Hence why we're wondering if it isn't actually Katy who's causing all the drama...

Mayer is set to perform on Sunday night and Swift is nominated for a handful of awards, including song of the year for "Shake It Off." Wonder if they'll cross paths?

Kim Kardashian made headlines on Friday for her raunchy full-frontal nude spread in Love Magazine, and we were so focused on that we almost failed to realize that she had done something else rather dramatic: The reality star chopped off a bunch of her gorgeous dark hair! Hey, at least she didn't dye it blonde again...

Kim stepped out with mom Kris Jenner and showed off her long bob, and she later posted a selfie on Instagram in which it appears to be even shorter! While she could easily throw extensions back in her tresses, we're wondering what sort of look she'll be rocking on the red carpet this Sunday at the Grammys...

Rihanna went to dinner at Giorgio Baldi last night, and while that's not news, we couldn't help but notice that the 26-year-old R&B star was looking extra glamorous in this gorgeous white outfit. Loves it!

RiRi will take the stage with Kanye West and Paul McCartney to perform their new song, "FourFiveSeconds," at the Grammys tomorrow night, but apparently she's worried about her ex-boyfriend Chris Brown being there. As you may remember, back in 2009 the former couple got into a horrific brawl after attending a pre-Grammy bash, which put RiRi in the hospital and saw Chris pleading guilty to felony assault charges.

"She has a big performance and she wants it to be her night," a source told HollywoodLife. "She doesn't want it to be dominated by everyone leaving the show talking about Chris and Rihanna in the same building. The Grammys are about the celebration of music and Rihanna has a job to do, she wants it to be drama free so she wants Chris not to be there. She will not tell him personally but feelers have been sent out that she doesn't want him there and hopefully he will listen."

Guess we'll find out tomorrow!
