Julia Louis-Dreyfus has had her last chemo treatment, and to celebrate, the actress took to Instagram to share a video of her grown sons lip-syncing to Michael Jackson’s “Beat It.”

“Ain’t they sweet?” she said of her kids. Julia was diagnosed with breast cancer in September the day after winning an Emmy for Veep. Since then, she’s been sharing her journey and support from the world on social media.

My beauty boys @henryhallmusic @charlie_hall made this for me today, my last day of chemotherapy. Pretty swell, right? Ain’t they sweet?
