CANCER DIAGNOSIS. Jen Arnold, who stars with her husband Bill Klein on TLC's "The Little Couple," is undergoing treatment for a rare type of cancer. The Houston neonatologist told People magazine, "I am very fortunate as the prognosis is good. While there is never a good time to get news like this, getting it just as we are building our new family is tough in many ways." Arnold, 39, and Klein, 38, are parents to son Will, 3, adopted from China, and daughter Zoey, 2, recently adopted from India.
