Jared Padalecki was recently in a car accident but is fortunately recovering.

However, he is not the only person on the “Walker” set going through a hard time.

On Monday, he tweeted about his co-worker, Kathy Miller.

He revealed that she is currently trying to beat leukemia.

He said that she is “fighting a hard fight; with grace, class, humility, and determination.”

Padalecki added that he was “so honored to be part of her support circle.”

He posted a link to her GoFundMe page on his Twitter profile.

Fans have raised about $48,000 dollars so far, just shy of her $50,000 dollar goal.

Miller is currently undergoing chemotherapy and doctors are “optimistic” that she will beat leukemia.
