Justin Bieber's Christmas album seems like it's set to be the next big thing!

Bieber and mentor Usher debuted their recording of classic Christmas tune "Chestnuts Roasting On An Open Fire" on Monday, and, of course, Beliebers went crazy!

Justin re-Tweeted one fan's Tweet, which read, "i am cryin happy tears lol i am at school but #chestnuts is just so beautiful <3"

God bless us, everyone!

On Sunday, Madonna hit the BFI London Film Festival for the U.K. premiere of her critically panned directorial debut, W.E..

Indeed, the critics had already dissed her, but fans, too, turned on Madge at the event. She was booed.

Fans had been waiting for hours in London's Leicester Square to see the pop icon, and jeered when she only stopped to talk to a few before entering the theater.

Madonna told Sky News amidst the yells that she identifies with the main character in her film, Wallis Simpson. Simpson, an American, was criticized for her relationship with the Duke of Windsor (Simpson is also portrayed in The King's Speech.) She said:

"I do know what it is like to be misunderstood on a global scale."

The singer met major criticism Sunday when news broke that her older brother is homeless, while Madge has millions.

Asked how she handles backlash, Madonna said: " ... criticism goes with the territory. I'm used to it. ... I don't read anything."

Zooey Deschanel nailed the National Anthem at Game Four of the World Series.

The 31-year-old New Girl actress certainly wowed the crowd at the game between the Texas Rangers and St. Louis Cardinals. After listening, we can certainly see why!

Following the performance, Zooey Tweeted:

“Would have loved to have watched the whole game but I had to catch a plane so I can go to work tomorrow. That’s all guys. I’m not a jerk."

Demi Lovato is scheduled to sing the National Anthem at Game Five. Click thru to read what the Disney starlet Tweeted about the honor.

While Kim is away, Kris Humphries plays!

As wifey Kim Kardashian was off in New York taping her reality show with sis Kourtney, new hubby Kris was in Miami taking in the local sights and enjoying the local flavor ...

The NBA star partied at the Fontainebleau's Liv nightclub September 30 and cozied up to a particular brunette on that fateful Friday night. A source inside the club that evening tells us:

"Kris was eating up the attention. All these girls were coming up to him and trying to flirt and he loved it, but he was really into this one chick. He kept leaning into her, talking in her ear. She took out her cell phone and was typing into it -- I think she got his number."

As the night progressed, it was unclear whether the two left together but Kim wasn't waiting for Kris at home -- she was off in New York, taping Kim and Kourtney Take New York. Since Kim left Kris solo, did the 26-year-old basketball hunk indulge?

"Kris is so young -- he's just doing what any guy his age does; it's just most guys his age aren't married. He's a professional basketball player and he's used to having access to whatever he wants. How's he gonna say no?" our source said.

Eeesh ... could Kim and Kris really be headed for Splitsville just two months after tying he knot???

Rachel Zoe's fashion mantra seems to be that it's better to be over-dressed than under-dressed!

Celebrity stylist Zoe and husband Rodger took son Skyler to the Malibu Country Mart on Sunday, where Zoe had Skyler dressed to the nines!

In an over-sized, striped newsboy cap, little Skyler was shielded from the sun ... but he didn't look too happy about his get-up!

The lineup just keeps getting better for this year's American Music Awards ... with Justin Bieber and Christina Aguilera added to the show. Gonna get dirrrrrrty!

Biebs and Xtina join fellow entertainers Maroon 5, Kelly Clarkson, Mary J. Blige, Pitbull and Katy Perry.

Larry Klein, the show's producer, revealed that Aguilera will be hitting the stage with Adam Levine to sing "Moves Like Jagger."

The AMAs will air November 20 on ABC.

Law and Order actress Mariska Hargitay happily celebrated her first Halloween with new daughter Amaya Josephine on Saturday night!

The mom-and-daughter pair went to the Light Up A Life benefit, put on by New York Presbyterian/Weill Cornell Phyllis and the David Komansky Center for Children's Health. Hargitay, 47, and her husband, Peter Hermann, are honorary chairpersons.

Mariska and Amaya were a gorgeous witch and an adorable pumpkin! More than 900 children and their families attended.

Hargitay and Hermann adopted Amaya about six months ago, and last week announced more good news: they'd adopted a son! The couple also has 5-year-old son August.
