'I'm excited and you know when I first got the book deal, I thought, "Oh what a great adventure this is going to be," and now that it's getting closer, I feel nervous in the sense that I've been able to always hide behind characters. 

'And now it's like, this is me, and it feels a little scary.' 

Anna playfully pleaded to her fans: 'Dear listeners: I would love it so much if you guys picked up my book. But please know, I am so scared.

'I feel like leaving the country for a while. I'm breaking into a sweat as we talk about it.'

She's also set to discuss being a married woman in Hollywood. 

Anna has been married twice: her first marriage, which lasted from 2004 to 2008, was to actor Ben Indra.
