We haven't heard the last from Whitney Houston. The singer's final song, "Celebrate," a duet with Jordin Sparks for their film Sparkle, recently made its debut on Ryan Seacrest's radio show.

It's classic Whitney, so die-hard fans won't be disappointed. Like her Grammy-winning pop from the '80s, this one celebrates life, love, and finding joy. It is the perfect showcase of a bold and beautiful voice that was snuffed out way to soon. Listen here:

We lost a star early this morning: Donna Summer, the Queen of Disco, passed away today at the age of 63 after a long fight with cancer. She leaves behind husband Bruce Sudano, their daughters Brooklyn and Amanda, and another daughter by a previous marriage, Mimi Sommer.

Donna's earned her title as the Queen of Disco with five Grammys. She was also the first artist to have three consecutive double albums reach number one on Billboard.

Donna was still performing and recording up to the very end. Here are six of our favorite Donna Summer songs -- but you know we could have just gone on and on with our favorites.

Say what you will about Aubrey O'Day, but the Celebrity Apprentice contestant certainly knows how to get her name in the news. Whether she's (still) talking about being fired from Diddy's girl group Danity Kane, dishing about Arsenio Hall's slut remark, or wearing next to nothing on the red carpet, she has a knack for finding her way into our Google searches. This go round, we're wondering how she'll fair on Sunday night's episode of Donald Trump's reality show -- it's then when we'll find out whether she, Arsenio, or Clay Aiken will get fired, but something tells me Aubrey has nothing to worry about.

Even though she temporarily left the show after a spat in the boardroom and has spared with numerous teammates, Aubrey has a certain je ne sais quoi. And no, that's not French for "enormous boobs in a small dress."

You have to love celebrities. Always asking for "privacy" during difficult times like divorce or death. And then turning around and blabbing to the media about their difficult times. It was only a few months ago that Bobby Brown was pleading for privacy for his daughter, Bobbi Kristina, in the wake of Whitney Houston's death. But apparently Dad doesn't know much about what Bobbi wants, because she's going to star in a new Lifetime reality series about ... Whitney Houston's death!

The upcoming "Houston Family Chronicles" will follow members of Whitney's family, including her mother, Cissy, and her daughter, Bobbi. Said Whitney's sister-in-law, Pat, who headed up the project:

The unexpected passing of Whitney certainly affects the direction of the show.  However, it is my hope that others will be enlightened as they watch our family heal and move forward.

Michael 'Mike D' Diamond, Rachael Horovitz, Adam 'Ad-Rock' Horovitz, and Adam 'MCA' Yauch of The Beastie Boys back in 2009Oh please, say it isn't so -- original Beastie Boys rapper Adam Yauch, also known as "MCA," has died. For anyone who grew up in '80s -- and surely many others -- this day marks the end of a rowdy, reckless, and damn fine era. Cue Gen X heartbreak across the world.

Beastie Boys' music, specifically "Licensed to Ill," permeates the memories of my wild and wonderful high school years. "You Gotta Fight for Your Right (to Party!)," "Paul Revere," "No Sleep Till Brooklyn," "She's Crafty," and "Brass Monkey" made good racket in many days and nights of celebrating youth for everything that's fabulous about youth -- being loud and unruly, speaking our minds, having fun, and driving around in cars with boys (real and Beastie), belting out some of the most poetically genius and playful lyrics of our time.

It's hard to believe he's gone.

If you've been thinking that your carbonated beverages haven't featured enough dead celebrities lately, great news! Pepsi has announced a whopper of a global marketing deal with Michael Jackson's estate. The campaign will reportedly include special edition can bearing The King of (Soda) Pop's image, chances to download remixes of Jackson's songs, and a television commercial.

According to Pepsi's chief creative officer, the campaign is intended to reinforce the brand's ties with pop culture. However, I can't possibly be the only one who instantly makes a tragic association when it comes to Pepsi and Michael Jackson. You know, one related to third degree burns and possibly a related life-long dependency on prescription drugs?

I have a big confession to make. I used to have the biggest crush on Ryan O'Neal. Seriously. Have you ever seen him in Paper Moon or Love Story? Or, my favorite (hey, I was just kid), The Main Event? This guy was smokin'! Oh, how the times have changed. Lately, Ryan is better known for his temper, his terrible parenting, and his arrest for drugs (which he claims belonged to his son Redmond.) Ryan is proof positive that you shouldn't pick your children's future father based on looks alone!

Sad, sad news for vampire fans: Jonathan Frid, better known as Barnabas Collins of Dark Shadows fame has passed away at the age of 87. 

Yes, I'm talking about the original Dark Shadows, that classic goth soap opera from the 60's that put vampires on the pop culture map -- and none of that would've been possible without Jonathan Frid at the center as Barnabas (yes, the character Johnny Depp plays in the upcoming Tim Burton remake).

Frid was more than watchable -- you literally couldn't take your eyes off the man. One could argue that Frid's menacing charm became a kind of benchmark for the undead on TV and in films ...

Meaning one could argue that without Jonathan Frid's Barnabas, there would be no Edward Cullen. (Cullen ... Collins ... coincidence? I think not.) There would be no Bill Compton. No Eric Northman.

Talk about scary!
