Michaels is reportedly in critical condition at an undisclosed hospital. According to the rep, Michaels was suffering from excruciating headaches earlier in the day.
Michaels underwent several tests, the rep says, including CAT Scans and MRIs.
Michaels suffered from a "subarachnoid hemorrhage" -- bleeding at the base of his brain stem.
Earlier this month, Michaels was rushed to the hospital after experiencing stomach pains -- he ended up having his appendix removed.
