(CNN)Lena Dunham has a lot of experience apologizing.
Dunham's latest mea culpa came Wednesday in a letter she wrote as a guest editor for The Hollywood Reporter's Women in Entertainment issue. The "Girls" creator apologized to actress Aurora Perrineau for publicly disputing her account of being sexually assaulted by "Girls" writer Murray Miller.
Last November, Perrineau told The Wrap that she had filed a police report accusing Miller of raping her in 2012, when she was 17 years old and he was 35. Miller denies the allegations and in August, the Los Angeles District Attorney's Office reportedly declined to pursue a case against him.
In her THR letter, Dunham admitted that she had lied when when she claimed she had "insider information" that would support Miller's innocence.
