Katy Perry, whose cleavage-baring performance was banned from Sesame Street, is taking her breasts elsewhere. The busty singer will be appearing on a special Christmas episode of The Simpsons. In the episode, the usually-animated characters will be transformed into muppets.

Ironically, Miss Perry's Simpsons appearance was taped before the Sesame Street drama started. However, Russell Brand's main squeeze is capitalizing now on what's now being referred to as "Elmo-gate." Over the weekend, she appeared on SNL as not only the musical guest, but also in a couple skits ... one in which she wears a low-cut Elmo shirt.

Katy's Simpsons episode will be airing on December 5th.

Rihanna was spotted on the Central Park set of her new music video "What's My Name", and the R&B hottie was in a fab mood even though she had been busting her booty all day long. Not only did she strike a pose for X17 photogs, but she snapped a few shots with adoring fans as she pranced around in a red wig, fishnets and a few other flashy items of clothing. We're not sure what she's wearing, but one thing is for sure -- that smile and smokin' hot bod are definitely the best accessories here!

Mariah Carey hit the stage in Singapore over the weekend ... literally.

While singing her hit song Make It Happen, the singer ... who is rumored to be pregnant, slipped while wearing her stilettos and went down to her knees while performing at the F1 Singapore Grand Prix.

After trying to recover gracefully from her fall, Nick Cannon's wifey makes a joke about having someone come out and get her shoes off because she should be "barefoot." Too bad the assistant that runs on stage has no idea what Mimi wants.

Oh, Mariah! We all know expectant mothers should be wearing flats.

Even though she sat out the premiere, it looks as if Sarah Palin will finally be making an appearance tonight on Dancing With The Stars!

Alaska's most famous mom was in Beverly Hills yesterday, going incognito (and showing off her sexy legs!) in a pair of running shorts and a hat, to do a little sightseeing with family members including her son Trig, daughter Bristol and adorable grandson Tripp.

Earlier this week, Bristol and her Dancing partner headed up to Alaska to visit Bristol's home state, and now Sarah is returning the favor by planning on supporting her eldest in the competish.

Not only did it take a minute for us to figure out that that was in fact Sarah in the sunglasses, we're struck by the fact that she's seemingly traveling without any security!

With Sarah campaigning for Bristol to take the mirror-ball trophy, do you think her daughter will have a shot?

Aww, these pictures are making us melt!

Over the weekend Pete Wentz, wife Ashlee Simpson-Wentz and their adorable son Bronx played at the park in Beverly Hills, and we can't believe how much he's grown! Think Pete and Ash are going to be adding any more cuteness to their perfect family? And no, we're not talking about pets!

Victoria Beckham was spotted taking her boys to a party in Beverly Hills on Sunday, and even though the temps were scorching hot over the weekend, The Posh One wore a super sexy outfit. And speaking of high temperatures, after all the heat Victoria and hubby David Beckham have received over the past week regarding those cheating rumors, she sure is keeping her cool!

On Sunday we snapped the first photos of Lindsay Lohan after her release from jail, and the actress went to the Dream Center near downtown LA, which is a church dedicated to serving the needs of inner city folks.

Lindsay was accompanied by mom Dina, manager Lou Taylor, sister Ali and BFF Eilat Anschel, and a source tells X17online exclusively that Linds went into the bathroom and broke down during her tour. The source added, "Lindsay heard stories from people who have had the same problems as her, and she was in tears. It certainly seemed like this was having a positive impact on her."

Lindsay (who was also rocking a brand new SCRAM under her boots) tweeted after her visit, "What a great place. The Dream Center is here in LA... had a nice time there today, it's so important to give back. I feel blessed." Lindsay met with children and families, and she even signed autographs and gave out handbags to some of the young girls.

According to our source, Lindsay's business manager/life coach Lou Taylor is a supporter of the facility and she was the one who helped organize the visit. Lindsay said she wanted to come back and visit the Dream Center, but she made it very clear that she wouldn't be staying there for her own rehabilitation. Though we'd like to believe that this was just Lindsay trying to be a better person, a source close to the visit tells X17online, "She's checking into rehab tomorrow and her manager felt that she needed good press." This is definitely a baby step in the right direction -- hopefully there will be many more to come!

These shocking photos of Lindsay Lohan playing with a syringe and and posing for pictures at a 2007 party send a strong message against drugs. It is uncertain whether Lindsay was actually injecting crystal meth or heroin or simply posing with an empty syringe for a series of sick photos. If the photos were a joke, it's clear drugs are no joke for Lindsay at this point in her life with the legal trouble she's in and the jail time she's facing.

Today, it seems as if Lindsay may seek treatment in a more appropriate drug rehabilitation program after the UCLA psychological treatment was deemed unnecessary for her. The actress, we're told by a source, is turned off to the idea of a traditional rehabilitation center but she's increasingly aware that it may be the only way to get Judge Eldon Fox back on her side and make it appear that she's sincere about getting healthy.

If these 2007 photos are any evidence, Lindsay was certainly in with the wrong crowd, not to mention Paris Hilton, pictured kissing Lindsay in these pix, being around the wrong people as well; though there is no evidence of Hilton having been around drugs at the party. Paris too, has had legal problems as of late and these images suggest a group of hard-partying Hollywood hipsters can get their more famous friends in trouble.
