It seems like Anna Faris is getting cold feet—about publishing her "Unqualified" book, that is. The 40-year old actress recently opened up during her "Anna Faris is Unqualified" podcast, where she spoke out about her upcoming memoir due on bookshelves this October. In it, she talks about her marriage to "Guardians of the Galaxy" and "Jurassic World" actor Chris Pratt, who she separated from in August. Their announcement came as a shock to their fans and film and TV viewers who were familiar with their work. The pair had nothing but praises to say about each other in red carpet appearances and interviews, but the separation seemed inevitable.

Some have attributed Pratt's superstardom, given that he's the face of two major blockbusters right now. He was also previously linked to his "Passengers" co-star Jennifer Lawrence, with whom he reportedly had really good chemistry with.

The 40-year old shared that in her book, she'll also delve into personal issues about "how I haven't felt comfortable in my own skin."

She added, "I feel, in a sense, that I got to always hide behind characters, and now this is me and it feels a little scary." It's unsurprising that the actress would have the pre-release jitters, especially now that the general public knows about her separation with husband, Chris Pratt.
