Bret Michaels Receives Flood Of Get-Well Wishes From Fans, Friends

'He's the nicest guy in the world,' says Sharon Osbourne of the ailing singer.

As [artist id="500964"]Bret Michaels[/artist] enters his sixth day in an intensive care unit following a brain hemorrhage, tributes and well-wishes continue to pour in from friends, colleagues and fans of the Poison frontman.

"It's devastating, and it makes you feel all these different feelings," Sharon Osbourne, who appeared with Michaels on "Celebrity Apprentice" and has known the singer for 30 years, told Us Weekly. "Your heart goes out to his family, your heart goes out to him. He's the nicest guy in the world. And then you start thinking about your own mortality. You start thinking, Oh my God. It just makes you appreciate how lucky we all are."

"Celebrity Apprentice" boss Donald Trump appeared Tuesday morning (April 27) on "Today," where he called Michaels a "competitor" who worked "maybe harder than anybody else."

"Apprentice" co-star and professional wrestler Bill Goldberg told, "I just spoke with Bret the day before he got sick, and I told him he had to slow down with his lifestyle. He was playing with his daughters in Arizona and was in really good spirits when we talked. I just hope that he can pull through from this and it acts as a wake-up call for him."

Michaels' official Facebook page, meanwhile, continues to be a venue in which fans can share information and messages of support for the 47-year-old rocker.

"Bret, I just wanted to say that I think you're a wonderful, talented and sweet person," wrote Elizabeth Ann Piotrowski. "I have two friends who pulled through similar situations, and I know you will too. It will take time and work, but I know you can do it! Lots of love and strength headed your way from me."

"Sending positive vibes your way for a full recovery!" Patricia Casper commented. "You gotta get through this for your kids. Everything else will fall into place when you feel you are ready to get back in the saddle and rock out!!"
