Friends star Matthew Perry, who tragically died on Saturday at the age of 54, had a secret crush on his co-star Lisa Kudrow, which apparently made filming the hit TV series a little tricky.Emergency services rushed to his home after receiving a call at 4.07pm that the star had suffered a cardiac arrest. But when they arrived, they reportedly found the star's lifeless body.
Even though no romance blossomed between them, Lisa still maintained a friendly relationship with Matthew and offered him support when he was battling addiction. He then started his recovery journey, which included rehab visits. Matthew wrote about this part of his life in his memoir, for which Lisa wrote a touching prologue.
