Katy Perry has reportedly started putting her heartbreak into songs as a way of dealing with her emotions
According to close pals, the 'I Kissed a Girl' singer has been writing down her feelings in a dairy since her relationship with Russell Brand became strained.
The 27-year-old singer is now referring to the diary for the lyrics for her next album.
"Ever since problems started to emerge, she penned her thoughts in a diary which she goes back to to draw upon for lyrics for her songs," the Sun quoted a pal as saying.
"She has always said that writing is almost a form of therapy for her and she would often be found in her dressing room on tour writing in her diary," he said.
"She spent a lot of time in Hawaii over Christmas writing lyrics to two of her latest tracks." Russell filed for divorce at LA Superior Court last Friday, citing "irreconcilable differences," he said.
The singer ha earlier documented Travis McCoy's alleged drug abuse in her album track, 'Circle The Drain'.
The lyrics went: "Thought I was the exception/ I could rewrite your addiction/ You could have been the greatest/ But you'd rather get wasted/ You fall asleep during foreplay/ 'Cause the pills you take are more your forte."
