Primrose Hill
She was Hester in "Fresh Fields", an 80s sitcom. Saw her just now1, she's smaller and greyer than I remember.
Celebrity spotting action, not actual stalking. Got to catch them all! Originally a popular feature of my site popex.com, so mostly from the early 2000s. 99% written by other people. Hopefully now with some bonus location content that was lost for a while.
