UPDATE: Ivanka Trump has just tweeted this message about the Celebrity Apprentice contestant: “My thoughts & prayers go out to Brett [sic] Michaels and his family. I wish him a very speedy recovery.”

Less than a week after telling fans that he “could have died” had it not been for an emergency appendectomy, singer Bret Michaels is currently being treated for a brain hemorrhage at an undisclosed location.

According to a report, the 47-year-old is listed in critical condition.

This latest medical development started late last night after the Celebrity Apprentice contestant complained of a massive headache. That’s when the bleeding at the base of Michael’s brain stem was discovered.

“After several CAT scans, MRIs and an angiogram, [doctors] decided to keep Michaels in the ICU and are running several tests to determine the cause. [It] will be touch and go for the next few days while he is under intense observation,” a source told People magazine.

After Bret’s appendectomy on April 12, the rocker was transferred to a rehabilitation facility that specializes in the care of diabetic patients. (Michaels has openly discussed his battle with diabetes.)

No word at this time what this situation might mean for the upcoming episodes of Celebrity Apprentice.
