In the video, her boys rocked out to Michael Jackson's "Beat It" and shared a sweet message to their mother in the beginning and end. "Pretty swell, right? Ain't they sweet?" proud mama Julia wrote in the caption.
And so, of course, Julia Louis-Dreyfus's two sons, Henry and Charlie, marked their mother's final day of chemotherapy with some incredible moves.
The short clip finds Henry and Charlie - whose dad is Louis-Dreyfus' hubby, actor and comedian Brad Hall, 59 - demonstrating they've both inherited a bit of their parents' comedy chops.
In September, Louis-Dreyfus announced she had been diagnosed with breast cancer a day after winning her sixth consecutive Emmy for her role as Selina Meyer on "Veep".
This is great material, and it's no wonder Louis-Dreyfus wanted to share with everybody! Clearly, the 56-year-old has had the best support system throughout her cancer battle, and to celebrate the big day, her two sons made her the most incredible video.
"We have every confidence she will get through this with her usual tenacity and undaunted spirit, and look forward to her return to health and to HBO for the final season of Veep".
Production on her show was halted, and she underwent multiple rounds of chemo.
"The expectation is we will shoot again", Rich said. After she completed her second round of chemo in October, the actress posted a photo of her with a drawn on moustache.
