Rihanna just loves to show off her naked body!

The sexy songstress posted the above photo after waking up in bed ... still wearing a piece of her Halloween costume from the night before.

RiRi wrote, "The morning after! Hello November."

RiRi and Chris Brown were among the many celebrities who dressed up for Greystone Manor's annual Halloween bash in L.A.

Nice tats, girl!

No one can say this supermodel doesn't eat!

Although she looks super thin, Alessandra Ambrosio made a pit stop at Ralph's in Brentwood to pick up some groceries.

Even when she's casual in spandex and a sweatshirt, this brunette beauty still commands attention.

We bet her royal sister wishes she could kick up her heels as regularly as Pippa does!

The Duchess of Cambridge's little sister stepped out in a bright red coat to party with friends at Lou Lou's in London last night, and it seems this royal sibling sure knows how to have a good time!

Her group stayed at the private members-only club, which is a favorite of Princess Eugenie and Kate Moss, until well after 3am. Although she is said to be enjoying new romance with 37-year-old investment banker James Matthews, her rumored beau was nowhere to be seen!

If there are two things Miss Pippa is an expert on, they are hitting the party circuit and dating wealthy businessmen!

Simply stunning!

More often that not, celebrities will not be caught dead without makeup, but not Marion Cotillard! The French actress strolled through LAX airport yesterday fresh faced, and we can't believe how naturally gorgeous she is!

The 37-year-old has a glow about her these days, and we think a lot of it has to do with the joys of motherhood. "Since having Marcel, my life has been alight with him. One of the things I have learned recently is that I have the ability to be happy. I have found that in my family. And that is a new thing. And that hasn't always been the case for me - so I know how lucky I am," she recently revealed to Harper's Bazaar.

Tres jolie!

Chris Brown's road to superstardom hasn't quite been squeaky clean, but the R&B singer claims he has worked hard to get back into the public's good graces since the infamous Grammy weekend beating of his former - or dare we say current - girlfriend Rihanna. Appearing on a new episode of MTV's "This Is How I Made It," the Grammy winner opens up about night that changed the path of his career forever.

"Having to get personal opinion back and having to gain personal success back, you know, it's not all the way back you know. But it's one of my most humbling experiences," he confessed. Although many believed his outburst would destroy his career and make it impossible for him to make a comeback, Breezy soldiered on in hopes he could change people's minds.

"My story or my life or my legacy can hopefully show them that once you're down, that don't just mean you're down forever. You never let up," he added.

The "Turn Up The Music" crooner was back in court for another probation progress hearing yesterday, and his lawyer Mark Geragos requested permission for his bad boy client to go on an upcoming world tour. When the chart topper attempted to speak up in the courtroom, Geragos shut him down, sniping, "I don't dance, you don't talk." Snap!

Let's just hope you realize you used your one "Get Out Of Jail Free" card CB!

Brown's episode of "This Is How I Made It" airs Saturday at 12pm ET on MTV.

Looks like Justin Bieber has been working out!

The teen sensation flexed his bulging biceps during a recent red carpet appearance while on his Believe World Tour.

Along with the photo, the following was posted, "Jb you think you jacked or sum???”

We'll answer that. Totes!

Did Toni Braxton have some work done?

The "Unbreak My Heart" singer arrived at Mr. Chow in West Hollywood looking a bit pulled back and ... um, tighter in the face region.

Although we couldn't get beyond her new look, we'll admit, Ms. Braxton looks stunning in red.

Thanks for the wave, Toni!

She's suing mad!

Following a bizarre In Touch report that claimed Amanda Bynes exhibited more disturbing behavior recently at a tanning salon in NYC, the actress is shooting down the rumors and setting the record straight. If you believe her, that is!

Apparently, the She's The Man star wandered out of her tanning booth completely naked and didn't care who saw her, then slowly made her way back into her room as she trailed her fingers along the wall and creepily laughed, but the 26-year-old vehemently denies the report and plans on taking legal action against the publication.

"I'm suing In Touch for printing a fake story. I'm not "troubled." I don't get naked in public. I'm 26, a multi-millionaire, retired. Please respect my privacy," she told Us in a statement yesterday.

Multi-millionaire?! We guess a bunch of B-list movie paychecks really add up!
