Bret Michaels could stage yet another comeback sooner than expected.

Doctors say it is possible that Michaels, the outspoken 47-year-old former Poison frontman currently competing on "The Celebrity Apprentice," could be healthy enough to appear on the NBC reality series' live finale on May 23. Michaels, one of seven stars remaining in the competition, has been in intensive care since suffering a brain hemorrhage last week.

Michaels, who was diagnosed with Type 1 diabetes at age 6 and underwent an emergency appendectomy April 12, was rushed to an undisclosed hospital last week with a severe headache. He was later diagnosed with a subarachnoid hemorrhage, which causes bleeding in the fluid-filled spaces around the base of the brain. The cause of the hemorrhage is still unknown.
