That smile. That body. That hair. Farrah Fawcett, who for much of the mid to late 1970s was the compulsory poster that adorned the bedrooms and school lockers of teenage boys, died after a long battle with cancer.

At first blush, it’s hard to pinpoint exactly why Farrah Fawcett was so famous. She was a 1970s pinup girl, yes, with her blindingly white smile and her suggested nipple on millions of teenage bedroom walls across America. At the end of the day, Fawcett, who died Thursday at 62 after a long bout with cancer, was a Hollywood celebrity heroine - brave yet broken, strong yet victimized, worldly yet innocent. She was the star of her own life.

Meanwhile another tragedy transpired as Michael Jackson died of a heart attack in a Los Angeles hospital, just weeks before he hoped to resurrect his four-decade long career with a series of sold-out shows in London. The King of Pop, 50 leaves behind three children. Meanwhile, from Bloomberg to Drudge, updates on Michael Jackson's death and life continue. Jackson's life was a mix of stardom, tabloid fodder and legal woes to include allegations of sexual abuse.

TV networks aired special programs on Michael Jackson and Farrah Fawcett, while newspapers were in over their heads with front page re-shuffling – two breaking stories in one day! But nothing compared to the buzz and speculation on Twitter, with Michael Jackson dead of heart disease, then with Farrah Fawcett now dead of cancer. Miley Cyrus, Ashton Kutcher and Lindsay Lohan are just some of the celebrities who have used Twitter to express their great sadness at the deaths.

Major Stars and practially everyone in the Twitter-Wood feed managed to tweet their reactions to the loss of both Fawcett and the King of Pop.
