LOS ANGELES (AP) — Bret Michaels is in critical condition suffering from a brain hemorrhage.

Michael's publicist, Joann Mignano, confirmed a report on People magazine's website Friday that said Michaels was rushed to intensive care late Thursday following a severe headache, and that doctors discovered bleeding at the base of his brain stem.

Mignano said tests are being conducted and no further information was available.

The 47-year-old reality TV star and former frontman for the '80s rock band Poison had an emergency appendectomy last week. He said on his website that although the surgery "has taken its toll," doctors expected him to make a full recovery.
