The former talk show host on the troubled singer.

As BRITNEY SPEARS undergoes evaluation at the UCLA Medical Center, ROSIE O'DONNELL is using her blog to talk about how the embattled pop star and her family could never have foreseen her future troubles when she first became famous.

She writes, in part: "They could not have known at the start that this would be the result. It is sold as the answer," while adding, "she wanted it, the mothers always said, as way of both apology and explanation."

Rosie also expresses her desire to help Britney: "If I had a magic wand, I would will her the strength, Windex all windows, watch the sun warm her soul."

Rosie concludes by writing: "All together now, we pray."
