(JTA) — Lena Dunham, the creator and star of the HBO series “Girls,” has been hospitalized and will undergo surgery. Dunham, 29, was taken to the hospital Saturday morning, a spokesperson for the actress said in a statement, after reportedly suffering the rupture of an ovarian cyst, part of her ongoing battle with endometriosis, a painful disease that reportedly affects at least 6.3 million women in the U.S. She has been public about the effects of the chronic disorder, in which tissue that normally lines the uterus grows outside the uterus. In a Facebook post early last month, Dunham said she would not be doing any interviews prior to the “Girls” season premiere on Feb. 21 due to the illness. Dunham, who is Jewish, also writes and directs the HBO series “Girls,” now in its sixth season, about a group of 20-something women living in Brooklyn, New York.
