Jen Arnold -- one of the stars of TLC's The Little Couple -- has cancer.
Jen made the announcement this morning (Friday). She says, ""I have recently been diagnosed with a rare type of cancer and am currently undergoing treatment, including surgery and chemotherapy. I am very fortunate as the prognosis is good." She did not disclose any specifics.
Jen and her husband, Bill Klein, are the adoptive parents of three-year-old Will and two-year-old Zoey, who they recently brought home from India.
