"We have been friends a long time, and I'm very much in his corner," she explained. "I wanted to make sure that he was getting the best possible care, which he is, and that his prognosis was good, which it is."

But Sharon isn't the only woman watching out for Michael, she says the actor's marriage to Catherine Zeta-Jones is the best support he can get!

"He really married the right woman," Sharon said. "And I think that when you have the best person standing beside you, there's nothing more curative than love."
