Let it snow, let it snow, let it snow .... on Mariah Carey, hubby Nick Cannon and their 19-month-old "dem babies."

The family of four braved the snowy Aspen weather for this adorable Christmas photo.

Mimi posted these pics with the following, "A Carey-Cannon Christmas, the most festive yet! Merry Christmas to all!!”

What a beautiful family!

Rihanna and Chris Brown are back on ... BIG TIME!

The on-again-off-again-on-again couple attended the Lakers/Knicks game together and left hand in hand.

RiRi and Brown haven't been seen together like this since the R&B singer assaulted the "Umbrella" songstress back in 2009.

Brown has reportedly dumped Karrueche Tran in favor of Rihanna.

Check out the photo RiRi posted on Twitter with the caption: "Thug Life #merryChristmas.”

This love story never seems to end!

Taylor Swift and Miley Cyrus are two singers who are in the holiday spirit all year long ... at least when it comes to being generous!

The two ladies have topped DoSomething.org's most charitable stars of the year list.

Swift, 23, recently donated $4 million to the Country Hall of Fame museum. Tay was also awarded the Ripple of Hope Award from the Robert F. Kennedy Center ... which recognizes celebs for their charitable efforts.

As for Miley, the "Can't Be Tamed" singer put her star power behind Saving Spot! Rescue, a non-profit dedicated to finding dogs from high-kill shelters a home.

DoSomething.org's list also included Lady Gaga, Justin Bieber, Channing Tatum, Selena Gomez, Robin Roberts, LeBron James, Ian Somerhalder and Pink.

Birthday boy Ryan Seacrest turned 38 on Christmas Eve and celebrated his big day with girlfriend Julianne Hough and family at Cecconi's in West Hollywood.

Although it was the American Idol host's celebration, we have a feeling his ladylove was hoping it would be the perfect time for her mega-rich beau to pop the question.

Perhaps these two will end this year as an engaged couple. Come on, Ryan ... no better way to ring in the new year than with some engagement bling!

Ben Affleck has admitted to enjoying politics, but the hunky actor isn't running for Senate just yet. The father of three released the following statement:

“I love Massachusetts and our political process, but I am not running for office. Right now it's a privilege to spend my time working with Eastern Congo Initiative (ECI), supporting our veterans, drawing attention to the great many who go hungry in the U.S. everyday and using filmmaking to entertain and foster discussion about issues like our relationship to Iran.”

Over the weekend, Affleck appeared on CBS' Face The Nation to promote Argo and said he has "a great fondness and admiration for the political process in this country" ... leaving many asking if he'd be seeking a Senate seat in Massachusetts.

Argo is a CIA thriller about an attempted rescue of American diplomatic personnel in Tehran during the 1979 hostage crisis.

Back to daddy duty, Ben.

Chris Brown and Rihanna arrived at today's Lakers/Knicks game today - TOGETHER - and they're even sitting together, court-side, right now!

It's the pair's first public appearance since Chris' assault on Rihanna back in 2009. Since then, Ri slowly started to confess her love for Brown on Twitter and in her infamous Oprah interview. Chris even dumped g-friend Karrueche Tran because he was "in love with two women," according to a short film he made just months ago.

Does this mean Chris and RiRi are back ON?

Paris Hilton and boyfriend River Viiperi jetted back to L.A. Sunday to spend Christmas at home after a week-long ski trip in celebrity hotspot, Aspen.

Queen P and her beautiful boy were all smiles after their romantic trip where they stayed in a $2000/night suite at the Little Nell -- the most luxurious hotel in the chic Colorado ski town.

You might think Paris would kick her feet up and sip hot chocolate all day, but nooooo .... this heiress digs into the powder on the ski runs and tears it up with River on the snowmobile trails! Check out this adorable pic of the couple during their last, adventurous day in Aspen:

After weeks of rumors and reports, Jessica Simpson finally confirmed her second pregnancy Tuesday on Twitter, posting this adorable pic of 8-month-old daughter Maxwell with "Big Sis" written in the sand in front of the little tot.

Jess captioned the photo: "Merry Christmas from my family to yours!" -- hers, a growing family with fiance Eric Johnson.

Simpson signed on as a Weight Watchers spokeswoman after her first pregnancy and lost over 50 pounds after giving birth in May. The Twitter page for the weight loss program read today, "Your WW family is so thrilled for you. What an amazing year you've had!"

An amazing year, indeed. Now wouldn't it be even more amazing if the soon-to-be second-time parents tied the knot before Jan 1?!
