Bret Michaels Health Update

ET has the latest on Bret Michaels' condition.

A source close to the family of the 47-year-old Poison frontman and "Celebrity Apprentice" contestant tells ET that Michaels will soon be undergoing surgery to relieve swelling around his brain. His condition is said to be deteriorating following a massive hemorrhage he suffered last Thursday.

Some believe it was an accident last June at the Tony Awards, where he collided with a set piece while performing on stage, that may have led to the problem.
