The `Total Recall` actress - who is engaged to Justin Timberlake - says penning her own verses helps her stay in touch with her spiritual side.
She said: "I like being able to write when I find the time to get into it.
"I love reading poetry and I`ve written poetry myself since I was in school.
"It`s very calming and spiritual to be able to get in touch with emotions and states of mind to write poetry."
As well as writing, the 30-year-old beauty - who scaled Mount Kilimanjaro in Tanzania in January 2010 to raise awareness of environmental issues - loves spending time outdoors, which she believes stems from her upbringing.
She added in an interview with The Sun newspaper: "My father was always telling me to go outside and appreciate nature.
"I was raised by hippie kind of parents and the wild and open spaces were something I was taught to value. I had a really great childhood and I still love being outdoors and having a healthy respect for nature.
"That`s one of the reasons I wanted to go to Kilimanjaro to draw attention to the issue of global warming.
"It was the hardest thing I ever did in my life but I`m glad I made the journey. It was a once-in-a-lifetime experience."
