Bret MichaelsBret Michaels still plans to show up to the "Celebrity Apprentice" finale on Sunday -- and if all goes well, win a lot of money for diabetes while he's at it!

Bret's rep tells PEOPLE, "As far as I know, Bret will be there unless his doctors tell him otherwise."

Michaels -- who will face Holly Robinson Peete in the final boardroom meeting with Donald Trump -- suffered a warning stroke this week, after a major brain hemorrhage last month.

His rep adds, "We're cautiously optimistic that he will attend the finale. But ultimately, it's up to his doctors."

Bret's winnings would benefit The American Diabetes Association if he's "Hired."
