"Celebrity Apprentice" kingpin Donald Trump says he is "deeply saddened" in response to news reports that former Poison rocker Bret Michaels has been hospitalized in critical condition due to bleeding at the base of his brain stem.

"My thoughts and prayers are with him and his family at this time," Trump tells ET. "He's a great competitor and champion and I hope he will be fine."

Michaels is a competitor on the current season of "Celebrity Apprentice" on NBC opposite such stars as Cyndi Lauper, Sinbad and Sharon Osbourne.

The Associated Press reported that Michaels, who was recently hospitalized after undergoing an emergency appendectomy, was rushed into intensive care Thursday night for having a severe headache, and doctors subsequently found that he was bleeding at the base of his brain stem.
