It's not very often that a young celebrity's sudden death is found to be from natural causes, and unfortunately, it seems rapper Chris "Mac Daddy" Kelly's untimely passing is no exception. When the news hit yesterday that the 34-year-old -- best known as half of the '90's group Kris Kross -- had been found unresponsive in his Atlanta home, no cause of death was declared. Today, however, authorities in Atlanta say they are investigating the case as a possible drug overdose.

Paramedics initially responded to Kelly's Atlanta home around 3 p.m. on Wednesday after his mother called 911. He was rushed to a nearby hospital, where he was pronounced dead a few hours later. According to a police report obtained by TMZ, Kelly's medical emergency can be traced back to a dangerous mix of drugs he took the night before.

In tragic news tonight, rapper Chris "Mac Daddy" Kelly has been found dead. The 34-year-old was best known as half of the 1990s group Kris Kross. 

If you lived through the 90s it's impossible that you didn't hear their hit song "Jump". It stayed at number one on the Billboard charts for eight weeks, and was played in clubs incessantly for years after. They were also known for their penchant for wearing their clothes backwards, and more than a few copied the look back in the day.

Our condolences to the family and friends of Divinyls' singer Chrissy Amphlett, who died yesterday at the age of 53 after battling breast cancer and multiple sclerosis. Though Divinyls recorded five albums between 1982 and 1996, the band is best known for their 1991 hit "I Touch Myself", due in no small part to Amphlett's trademark look -- a schoolgirl uniform with fishnets and long red hair -- and seductive vocals. As her husband, former Divinyls drummer Charlie Drayton, said in a statement:

"Chrissy's light burns so very brightly. Hers was a life of passion and creativity; she always lived it to the fullest. With her force of character and vocal strength she paved the way for strong, sexy, outspoken women."

Comedian Jonathan Winters, who was most famous for his stints on the Tonight Show and Mork and Mindy, died at home Thursday of natural causes at the age of 87. Winters was a beloved funnyman with razor sharp wit and timing whom Albert Brooks said "invented a new category of comedic genius." While he never had a breakout role, he was wildly known and appreciated for his comedy albums and character parts. With just one eyebrow raise, he could have you doubled over in stitches.

No matter if you're a giant Winters fan or just hearing of him for the first time, these 7 funniest clips of his will make you dearly miss the old bastard.

The world seems to be taking Roger Ebert's death from cancer hard. I've been amazed by all the heartfelt articles and comments posted in his honor. The man and his work touched so many, but perhaps the most memorable words about him of all were in his wife Chaz Ebert's tribute to her husband and their life together. 

The woman who was not only married to Jim Henson but who was his partner in creating those beloved Muppets, Jane Henson, lost her battle with cancer on Tuesday at the age of 78.  What an incredible legacy those two have left the world!

I have to confess -- I never knew that Jim Henson had a creative partner while coming up with everyone from Kermit the Frog and Miss Piggy, to Sesame Street’s Big Bird and Cookie Monster! Did you?

Man, does MTV ever have a messy situation on their hands with their reality series Buckwild. You may remember the initial controversy when West Virginia Senator Joe Manchi demanded that MTV cancel the series to avoid "ugly, inaccurate stereotypes about the people of West Virginia," and the show came under fire again in February when cast member Salwa Amin was arrested for dealing heroin and oxycodone. Now, shockingly, 21-year-old Buckwild star Shain Gandee was found dead in his truck with two others on Sunday morning.

The vehicle and bodies were found by one of Shain's friends who had been searching for him since he went missing over the weekend. No foul play is suspected, but with this latest tragedy, there's a fresh wave of demand for MTV to pull the plug on the show.

Sad news out of Hollywood today: Bonnie Franklin, star of the groundbreaking hit sitcom One Day at a Time, has passed away at the age of 69 from pancreatic cancer. And though she'll be remembered for many roles on stage and screen, Franklin's "Ann Romano" will always hold a place of significance in TV history simply because she was a single mother -- and when the series premiered in 1975, single moms hadn't exactly made it to prime time yet. In fact, just five years prior, the same network had doubts about letting Mary Tyler Moore play a divorcee -- on her own show!

And Ann Romano wasn't some glamorized version of a single mom, either.
