The 41-year-old singer/songwriter struck up a friendship with Fisher after his ex-girlfriend Dixie Chassay, whose family are long-time friends of the Hollywood star, introduced them, reported Female First.
Blunt says Fisher's passing at the age of 60 last year came as a huge shock to him and he still has not quite processed the loss of his pal.
"She was just the most incredible person. She was a hugely bright person and her brain just jumped between subjects and she was an incredible writer and comedian in her own way. Life will definitely not be as much fun now that she's not around," the singer said.
