According to the Los Angeles Times, Katie was given a cheap, throwaway phone by a friend so she could talk to her attorney without Tom getting wind of her plans.
When Katie made her move on June 28, she had already hired three law firms in three separate states. The divorce took Tom completely by surprise.
Tom returned to work on the set of his new (aptly titled) movie Oblivion yesterday, where he was greeted by sympathetic hugs from his colleagues.
Tom and Katie came to a speedy out-of-court settlement on Monday, just ten days after Katie filed for divorce. Although the details of the agreement are still under wraps, it's rumoured Tom could be forking out as much as $50 million to his soon-to-be ex-wife.
