Surrounded by the paps as she ambled down the sidewalk on what was obviously a slow celebrity day, American Idol runner-up Katharine McPhee gamely kept her cool as she was hounded by pushy press and bright, flashing bulbs. She seemed fine if a little frazzled in the middle of the media crush, but she was all on her own until a single heroine stepped forth.

Found out who saved McPhee - and how - by viewing the video after the jump.

The woman in the video is being billed as a homeless woman; the validity of this statement has not been verified.
