It's no act - these TV cutie pies are sweet as can be. The Love Boat's Lauren Tewes helped passengers find love on the high seas as fetching Cruise Director Julie McCoy. On Mad About You Helen Hunt was the terminally perky Jamie Buckman. And Karen Valentine helped motivate the students of Walt Whitman High as beloved student teacher Alice Johnson in Room 222, and later as a regular on Love American Style.
