CAREER-CHARGING Cameron Diaz is getting back in the saddle for a new role — and sources tell GLOBE she's got rom-com rivals looking nervously over their shoulders as she vies to be queen of 50-something American Sweethearts!

The 52-year-old mother of two is set to star in the action-comedy Bad Day, in which she plays “a single mom fighting to keep one little promise to her daughter on the absolute worst day of her life,” according to a Netflix release.
