Is that really you, RiRi?

The "S&M" singer was almost unrecognizable as she left her hotel in Stockholm, Sweden all wrapped up in an oversized jacket, army baseball cap and shades, on Thursday night.

But although the sexy songstress was in a head-to-toe disguise, she still managed to stop and pose for pix with several of her fans, who were waiting outside the hotel in the freezing cold.

Unfortunately for her Swedish fans, Rihanna was forced to cancel yet another show Wednesday night, following her visit to the hospital with the flu on Monday. RiRi posted a Twitpic of herself hooked up to an IV drip in an attempt to get better quick, but it seems the singer is still feeling under the weather.

Get well soon Rihanna!

Lindsay Lohan's mom, Dina, is opening up about her daughter's upcoming Playboy shoot. She tells The Insider:

"It was an opportunity for her. … She's 25 years old now, so it was her ultimate decision. … It will be tastefully done. … I've seen [the photos]. … She's really great in front of the camera."

As for her recent community service at the LA County Morgue, Dina adds:

"She witnessed a lot of things that were traumatizing. But certainly we're at a fortunate place; I worked so hard to get to where we are, and there are so many people dealing with far worse than I'm dealing with, so I really can't cry in my life, because my kids are healthy and happy and there are so many other people that aren't. So we just have to grab our blessings when we can."

Dina, who admits Lindsay made a mistake back in 2007 by driving under the influence, says she can't wait to put the court drama behind her because "it's been four years of torture ... we just want this over."

Michael Lohan's ex also confirms she's writing a book. Find out if she plans to write about Lindsay's court drama in the above video.

Justin Bieber stopped by the Today Show to set the record straight regarding Mariah Yeater's claims that he fathered her son.

While surrounded by hundreds of screaming fans, Bieber, 17, told Matt Lauer:

"None of those allegations are true ... I know I'm going to be a target, but I'm never going to be a victim. It's crazy, every night after the show I've gone right from the stage right to my car, so it's crazy some people want to make up such false allegations. But to set the record straight, none of it is true."

Yeater, the 20-year-old woman who claims she slept with Justin Bieber, says she and Bieber had sex following his concert at the Staples Center on October 25th of last year ... resulting in the birth of her son, Tristyn Anthony Markhouse Yeater.

Bieber adds, "Never met the woman."

However, if the alleged sexual encounter is proven to be true, Yeater could be charged with statutory rape due to the fact that Bieber would have been only 16 at that time.

He may have packed on a few pounds to play J. Edgar Hoover in the upcoming biopic on the founding FBI director's life, but Leonardo DiCaprio looked like his usual dapper self while attending AFI's Opening Night Gala in Hollywood, on Thursday.

The Great Gatsby star has been garnering lots of Oscar buzz for taking on the role of one of the most important characters in American history. Leo not only gained weight, he also donned prosthetic teeth, a bald cap, a device to reshape one nostril, latex body pads, colored contacts and layers of silicone applied to his face.

DiCaprio recently confessed of his decision to take on such a meaty role: "When I can’t immediately define the character, and there’s an element of mystery to it and still a lot to be explored, that’s when I say yes. I like those kinds of complicated characters. I just do.”

The Partay is over!

At the insistence of PETA, Reese Witherspoon has promised never to carry her $3,820 Chloe "Partay" python bag again.

The Oscar winner ditched the snakeskin purse after PETA noticed her toting it around LA and immediately sent her a video -- narrated by Walk the Line costar Joaquin Phoenix -- that detailed cruel practices used on animals for the sake of fashion.

After Witherspoon vowed to give up the bag, PETA said in a statement:

"We've long known Reese to be a kind person, so we're pleased -- and not surprised -- that she is hanging up her python bag for good. We hope Reese's honest mistake will serve as a reminder for all of us to be extra-certain that what we’re buying is mock croc or fake snake."

The Chloe bag isn't exactly legal either -- California outlawed the sale of snakeskin in 1970.

After a trip to the Byron and Tracey Salon in Beverly Hills, Kate Bosworth was all smiles as she showed off her newly coiffed 'do (and a "wedding" band on her left finger!), on Thursday.

The Blue Crush star was first spotted sporting matching rings with her beau, producer Michael Polish, at the Vogue Fashion awards in LA -- could they have secretly gotten married?

Bosworth recently opened up on her love for Polish, expressing: "He’s a special one. There’s nobody in the world I admire or respect more. When I look at him, it’s not a crazy infatuation, it’s more like we are each other’s life partners.”

It seems Kate has finally found "the one".

Selena Gomez was spotted jetting out of LAX on Thursday afternoon, and even though the teen Disney starlet was mobbed by fans and photographers, she giggled as she hopped out of her car and headed inside to go through security.

Selena didn't seem fazed when asked about boyfriend Justin Bieber's alleged baby mama Mariah Yeater, as she has far bigger things to worry about, like hosting MTV's European Music Awards this weekend. Yesterday she tweeted, "Packing for the #MTVEMA are you ready Belfast? Tune in Sunday Nov. 6th, big surprises for you guys."
