Rock Star group Creed's lead singer Homeless and Penniless, Shocking New Video

Scott Stapp -- the lead singer of Creed and on of the most successful frontmen in the '90s -- says the government has stolen his money and now he's so desperate, he can't afford rent or even food. 

Stapp just posted a 15-minute cry for help on his Facebook page, saying the IRS has frozen his accounts and the banks have conspired to rob him of his fortune.

The singer says his wife -- who has filed for divorce -- is trying to get him committed, falsely accusing him of doing meth and showing signs of paranoia. Her divorce docs reportedly contain text messages from Stapp which say, among other things, "Florida is not safe. Biological weapons on the way."

Stapp sent another text which read, "I wouldn't doubt it if the CIA is behind Alcoholics Anonymous." And he warns, "God created you and now God is ending you."
