LOS ANGELES -- Rocker turned reality star Bret Michaels remains in critical condition at an undisclosed hospital after suffering a brain hemorrhage Thursday night.
Doctors are still trying to find the source of his brain hemorrhage, and the 47-year-old former Poison front-man is under 24-hour surveillance, according to an update on Michaels' website.
"Further testing this week will help locate the source of the bleeding," Monday's update stated.
The rocker's tour manager, Janna Elias, has been posting the online updates.
"As we all know Bret is a fighter and we are hopeful that once all is complete the slurred speech, blurred vision and dizziness, etc. will be eliminated and all functions will return to normal. Everyone at Michaels Entertainment would like to thank all fans and friends for their continued thoughts and prayers through this difficult time."
Though there were reports circulating that Michaels' condition had stabilized, Elias, who is reportedly at the rocker's hospital bedside, said on Sunday that he remains in critical condition.
"There are several incorrect reports on Bret's condition. Bret remains in critical condition at an undisclosed location. Further tests are being ran and information will be updated in the coming days," she said in a statement.
The rocker is currently a contestant on Donald Trump's NBC competitive reality series, "The Celebrity Apprentice." He has also starred on VH1's "Rock of Love."
Donald Trump said in a statement Friday that he was "deeply saddened" to hear of Michaels' condition.
"He's a great competitor and champion, and I hope he will be fine," Trump said.
On "Celebrity Apprentice," Michaels has been concerned of late with his daughter's health.
She has been tested for diabetes after Michaels said recently "she is showing all the signs."
