When news of Murphy's death made headlines in December (09), fellow Clueless stars Alicia Silverstone and Donald Faison immediately paid tribute to the 32 year old.
And Dash has finally revealed how Murphy's passing affected her.
In an interview with GlobalGrind.com, she says, "When I heard (about) the death of Brittany, I was in a state of shock and filled with sadness. She was a sweet, funny girl with this incredible light around her. To have her leave us so soon is a great loss."
