Julia Louis-Dreyfus wants everyone to know she’s a fighter.

The “Veep” star posted a photo of herself Thursday sporting a hoodie and a drawn-on mustache on Instagram to update her fans on her fight against cancer.

“Chemo #2: finito,” the caption read. “We are NOT f***ing around here.”

The actress revealed her breast cancer diagnosis last month and since then has gone about living her life.
