Samantha Who? star Christina Applegate has been diagnosed with an early form of breast cancer. A spokesperson for the 36-year-old actress says in a statement, "Benefitting from early detection through a doctor-ordered MRI, the cancer is not life threatening. Christina is following the recommended treatment of her doctors and will have a full recovery."

The Office's Rainn Wilson, who woos Applegate in The Rocker, told TV Guide at the big-screen comedy's red-carpet premiere, "I understand she's going home very soon, and I'll reach out to her soon." Is Applegate the kind of gal who can beat this? "She's a fighter, definitely," says Wilson. Applegate's mother is a survivor of breast cancer, the most common form of the disease in women. - Matt Mitovich, with additional reporting by Carita Rizzo
