During the entire Katie Holmes-Tom Cruise divorce saga thus far, we've noticed how much Katie has focused her attentions on her fashion endeavors (not to mention her daughter Suri). So it comes as no surprise that even before serving Tom with divorce papers asking for full custody, the mother also took a big step to protect her fashion line Holmes & Yang: She fired Tom's daughter from the company.

A source tells The Hollywood Reporter that Bella, Tom's 19-year-old adopted daughter from his marriage to Nicole Kidman, was abruptly fired from her post at Holmes & Yang just two months before Katie decided to formally end the marriage. According to the source, the decision seemed out of the blue:

There was never any trouble between them. Bella called Katie ‘Mom.’ She was fired out of the blue, and once Katie filed for divorce, it all made sense. This was a carefully planned ambush. Katie didn’t want Bella working for her anymore because she was Tom’s kid.

Some have taken Katie's actions as a sign that she was gearing up to leave Tom for months before the surprising announcement. While we can only speculate on that matter, we do know that the recent divorcee has certainly had fashion on the brain during the months leading up to the split. During an interview in the August issue of Elle, Katie announced that Holmes & Yang will be hitting the runway come September Fashion Week. So at least now that the whole divorce thing is out of the way (they settled today!), she can continue to focus her energies on her fashion endeavors.

See how Katie's style changed over the years:
