Lena Dunham is recovering at home following emergency surgery.
The Girls star was rushed to hospital on Saturday after an "ovarian cyst rupture" but has taken to Instagram to insist she is doing well.
Meanwhile, her representative previously confirmed the news and asked for "understanding" at the difficult time.
They told PEOPLE magazine: "Lena Dunham has been very public with her personal bouts with endometriosis. This morning, she suffered from an ovarian cyst rupture and has been taken to the hospital. Lena will be undergoing surgery at an undisclosed hospital. We thank you for your understanding and hope that Lena's privacy will be respected."
