Before you read this week's diary, we asked each of the models to send home a video Valentine, and here's what Casey came up with.

I usually write about what I did this week in my journal, but I decided this week to do something different, since the theme for this week was emotions and ones we care about. I am going to write about how much I miss my friends and family. I know a lot of people have families that are unsupportive of them and friends that don't really care. But I am so lucky to have a loving family that will support me in whatever I do, and I am so glad that I have that. My family is a big reason for why I am here. I hope they all know I love them more than anything. My friends are the greatest. I only have a few but they will do anything for me, and I would do anything for them. We're seeing each other on our highest highs and our lowest lows. We support each other and call each other BS, and I am so glad I have them in my life. This week was great. The main part was the acting and I have a very theatrical background and being able to work with Perry was great, and being able to play off each other and truly create an entertaining scene.
