Poison frontman and current Celebrity Apprentice contestant Bret Michaels is in critical condition after suffering a massive brain hemorrhage. The 47-year-old rocker (and former Rock of Love star ) complained of headaches Thursday night and was rushed to the hospital, where he remains under intense observation. Just 11 days ago, Michaels underwent an emergency appendectomy. It is still unknown whether the hemorrhage is related to the appendectomy or Michaels' Type 1 diabetes. [EW]
