Louis-Dreyfus didn’t provide any further details about her diagnosis. Her rep told reporters in a statement, “Julia is incredibly grateful for the outpouring of support and well wishes.”

HBO told reporters in a statement that Louis-Dreyfus learned she had breast cancer just one day after the awards, and noted that the production schedule on Veep will be adjusted as needed.
“Our love and support go out to Julia and her family at this time,” HBO said in the statement. “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.”
Stars were quick to show their support of Louis-Dreyfus on social media, with her Veep co-star Tony Hale tweeting, “we love this woman.”
