little couple jen arnold 'Little Couple's' Jen Arnold shares bald chemotherapy photo, cancer treatment update

Jen Arnold, star of TLC’s “The Little Couple,” is undergoing chemotherapy for a rare type of cancer … but she’s staying positive throughout the treatment.

Arnold tweeted an update on her chemo on Friday (Dec. 27) after it was pushed back from before Christmas due to “low counts [which made meds] not safe to give.”

The smiling pic that showcases Dr. Jen’s newly bald head goes hand-in-hand with her outlook on her treatment. Arnold found a “silver lining” in the postponement: having “a better Xmas” with husband Bill Klein, their recently-adopted 2-year-old daughter, Zoe, and 3-year-old son, Will. “How could I not enjoy … First one with the kids,” Arnold says. “Not letting #cancer ruin our #Christmas.”

TLC will continue filming as Arnold undergoes treatment, and hopefully her positive attitude will have a positive effect on her health.
