Los Angeles ? Bret Michaels is expected to make a full recovery, according to his doctor.

The 47-year-old former Poison frontman’s will to live is “undeniable,” said Dr. Joseph Zabramski, chief of cerebrovascular surgery at the Barrow Neurological Institute at St. Joseph’s Hospital and Medical Center in Phoenix, who has been leading the team treating “The Celebrity Apprentice” contestant since he suffered 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 St. Joseph’s 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.

Other doctors said it is possible that Michaels could be healthy enough to appear on “The Celebrity Apprentice” live finale May 23. He is currently one of seven contestants remaining on Donald Trump’s competitive reality series, including pop singer Cyndi Lauper, reality TV diva Sharon Osbourne, celebrity chef Curtis Stone and actress Holly Robinson Peete.

Whether he’s fired or hired by Trump during the May 23 finale or in an earlier installment, Michaels’ representatives are still giving his music fans something to believe in. While his appearances scheduled through May 21 have already been postponed, Michaels’ other concert dates, including his summer tour with Lynyrd Skynyrd, are going ahead as scheduled.

“At this time, we are planning to resume the tour May 26 in Fort Smith, Ark., provided there are no further complications or setbacks,” said a statement posted Thursday on Michaels’ website by his tour manager, Janna Elias.
