Veep star, Emmy magnet and all-around comedy treasure Julia Louis-Dreyfus shared an impossibly sweet and silly video her sons made for her last day of chemotherapy. The actress/producer revealed last fall that she had been diagnosed with breast cancer.

Her sons Henry and Charlie crafted a special inspirational video for their mom’s important day with a pretty straightforward message. In the Instagram video, the two young men lip sync Michael Jackson’s “Beat It” with pep, moxie and some lovely choreo.

“My beauty boys @henryhallmusic @charlie_hall made this for me today, my last day of chemotherapy.” wrote Louis-Dreyfus in the accompanying caption. “Pretty swell, right? Ain’t they sweet?”

Julia Louis-Dreyfus has shared glimpses of her cancer battle online and messages of support she’s received from friends and family.

When she went public with her diagnosis, Louis-Dreyfus used her statement as an opportunity to place a spotlight on the need for accessibility in health care no matter the income bracket.
