"Grey's Anatomy" returns with an all new episode this Thursday on ABC, but during her visit to Access Hollywood Live on Tuesday, actress Jessica Capshaw revealed there is some Internet-related drama brewing behind the scenes too.

According to the actress, who plays Dr. Arizona Robbins, she and Patrick Dempsey are involved in an amusing Twitter photo war.

"We got into a Twitter pic war, where literally he was wielding his iPhone like it was a weapon," Jessica smiled as she told Billy Bush and Kit Hoover what's been going on with Patrick.

Jessica explained that Patrick, who recently joined Twitter, has become fond of posting photos of his cast mates, including her, in less than perfect poses.

"Patrick most likes to take pictures of me in compromising positions," Jessica explained of the amusing way they've been spending their down time on set. "[Like] when you're in the middle of taking a bite of a muffin, making a sun [squinting] face, doing something that's just not attractive."

Now, for all of Twitter to see, there are a host of unapproved photos circulating of Jessica and some of her fellow "Grey's" co-stars.

"He doesn't ask us [before posting]. We live in this world where it's like, it'd be nice if someone said, 'Hey! I just took this picture, I'm gonna Tweet it now," she explained.
