Poison singer Bret Michaels remains in a critical condition in hospital after being diagnosed with a brain haemorrhage, his publicist has said.
The US rock star, 47, was rushed to hospital in Los Angeles on Friday with a severe headache.
Michaels, who can be seen on US TV on The Celebrity Apprentice, was found to have had a subarachnoid haemorrhage, or bleeding onto the surface of the brain.
He is conscious and talking with slurred speech, his publicist added.
"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," a statement released by his publicist said.
Michaels, who has diabetes and who had his appendix removed in an emergency operation last week, rose to fame in the 1980s as the lead singer of Poison.
The rock band had hits including Every Rose Has Its Thorn and Unskinny Bop.
Michaels recently recorded a song with teen star Miley Cyrus.
Donald Trump's The Celebrity Apprentice was filmed several months ago but is halfway through its run on TV in the US - Michaels is one of the favourites to win.
"He's a great competitor and champion, and I hope he will be fine," Trump said.
