Perez Hilton tweeted his new blog post, which can be found here. It includes the picture of Dianna from the set yesterday (above).
Chord then tweeted Perez and said that he was the one who took that picture of Dianna! …and later that day they took a picture with Ted. I bet they were hanging out together all day on set ;)
So technically this is an Overgron pic too! A pic of Dianna taken by Chord. :D
