Ryan Seacrest, P. Diddy, John Mayer tweet about DJ AM's shocking death

DJAMandNic_Vespa_6499729_600 Friends and admirers of DJ AM  have been tweeting all afternoon about the shocking death of Adam Goldstein. 

He was found dead in his Soho apartment with drug paraphernalia scattered about. 

Miraculously, just a year ago, he had jumped through a fireball to survive a small-plane crash that killed four people on board.

Here are some farewell tweets from his peeps, including Paris Hilton, Ryan Seacrest, Katy Perry, John Mayer, Demi Moore and Perez Hilton.

 @parishilton Adam and I were friends since I was 15. He had a heart of gold and was one of the kindest, funniest and most talented men I have ever met.

 @petewentz R.I.P. . I'm sorry to loved ones. So unexpected.

 @ryanseacrest So sad the hear about adam. a very kind and generous guy
