Rihanna will perform on Saturday Night Live's Halloween episode this year, according to Rap-Up.com.

Mad Men's Jon Hamm will host the show, and Rihanna will be performing tunes from her fifth studio album, Loud.

This marks Rihanna’s second performance on the show. Can't wait to see what she wears!

How mature!

Selena Gomez recently appeared on BBC Switch's The 5:19 Show, and when asked about her pal Justin Bieber, the Disney cutie was definitely a bit harsh! Selena told the show, "He's a dork. He really is ... He's just not cool. I get it -- when he has his swag on, he's definitely cool, he's got it going on -- but when he doesn't, he's just funny."

The Kardashians have been spending quite a bit of time in New York over the past few months, and it looks like Kim and Kourtney have fallen in love with the city so much, they're going to shoot a spin-off show there!

Kim and Kourtney will start filming a spin-off of their E! series, Keeping Up With the Kardashians in TriBeCa, and according to the NY Post, they will stay in a penthouse at the Smyth Hotel for the next three months. Khloe will stay at home in Los Angeles with her hubby Lamar Odom, but the show will be similar to Kourtney & Khloe take Miami, as it follows Kim and Kourt expanding the family business and trying to find Kim the perfect man.

Scott Disick will reportedly live in the penthouse with Kourtney and baby Mason for the show, and we're hearing the three of them may relocate to New York permanently!

Mr. and Mrs. Zoolander (aka Ben Stiller and wife Christine Taylor) were spotted leaving AMMO restaurant in Hollywood last night, and the duo didn't seem bothered by the paparazzi at all. I guess when you've been in the industry this long (not to mention happily married for over ten years!) camera flashes are just part of a night out. Looks like they had a good time though!

After CNN anchor Rick Sanchez appeared on the Stand Up! with Pete Dominick SiriusXM radio show on Friday and commented that Jon Stewart was "a bigot" and that CNN was "run by Jews," the news network issued a statement announcing that he has been let go from his position. “Rick Sanchez is no longer with the company," the statement read. "We thank Rick for his years of service and we wish him well.“

Sanchez said there's racism in the media "not just [from] the right," but also "elite, Northeast establishment liberals" that "deep down, when they look at a guy like me, they see a guy automatically who belongs in the second tier, and not the top tier."

Stewart had no comment on the story, but insider tells The Hollywood Reporter he may discuss it on The Daily Show on Monday. Do you think Sanchez should have been let go for his statements? Click after the jump to hear the controversial radio interview and let us know what you think in the comment section below!

Yesterday we spotted Isabel Lucas running errands in Hollywood and Beverly Hills, but the Transformers hottie somehow found the time to slip home and change her clothes. The K. Stew hipster look is cute and all, but we'll take her in a dress any day of the week!

Kate Bosworth and her stylist/designer Cher Coulter have launched JewelMint.com, a website that allows members to share purchases with friends through Facebook and Twitter.

The monthly subscription fee is $29.99, and users will get access to one piece of exclusive jewelry each month from a collection designed by the ladies. Kate said in a statement, “It’s a natural extension of our friendship, our creative relationship and our love of fashion. We couldn’t be more excited.”

Maybe a clothing site is next? We'd kill to raid Kate's closet!

Miley partying in Paris last month

Underage starlets hitting the Hollywood clubs are nothing new -- but at 17-years-old and just barely graduated from the tween hit Hannah Montana, is Miley Cyrus too young to club?

Last night, Miley partied at one of Hollywood's hottest spots until 1:30am! Not only is it illegal for Cyrus to be in an over-21-club, but it's also against the strict 10pm curfew for minors (which could result in a fine of $250 -- somehow we think Miley can afford it.)

Now, despite her tween queen status, Miley has always seemed way wiser than her years. That's not really surprising, since she's been working since the age of 12! And she's already shattered her good girl image with, among other things, sexy costumes while promoting Can't Be Tamed and that scandalous lap dance with director Adam Shankman!

But after a Hollywood club crackdown in 2007 where the admittance of underage stars like Lindsay Lohan, The Olsens, Jesse McCartney and Rumer Willis (then all under 21) prompted the investigation of several hotspots by the Alcoholic Beverage Control, you would think a place like Voyeur wouldn't want to call attention to themselves by admitting one of the most famous (and famously) seventeen-year-olds in the country!

I guess they could argue, like Les Deux did at the time, that she wasn't served alcohol. But is that really the right environment for a teenager?

On the other hand, at 17, Miley's traveled the world and been in two long-term relationships with guys who were already in their 20s, and has worked pretty much non-stop for five years. Does she deserve to be able to blow off some steam with friends as long as she's not being served alcohol? Or is 17 still too young?
