I should’ve believed you – Lena

Lena Dunham issued a lengthy apology Wednesday to the actress who accused “Girls” writer Murray Miller of sexual assault.

In a column for The Hollywood Reporter, Dunham said it was “inexcusable” that she jumped to Miller's defense last year and publicly accused Aurora Perrineau of lying to police.

Perrineau (photo), an actress in “Jem and the Holograms” and “Passengers,” stepped forward last November to say Miller raped her after a night of socializing in Los Angeles County when she was 17 and he was 35, according to TheWrap.com.

In her initial, immediate statement defending Miller, Dunham claimed to have “insider knowledge” that exonerated him.

The “Girls” creator admitted Wednesday no such information existed, and she now believes “there are few acts (she) could ever regret more in this life” than suggesting Perrineau, now 24, fabricated her claim.

“I didn't have the ‘insider information' I claimed but rather blind faith in a story that kept slipping and changing and revealed itself to mean nothing at all,” Dunham wrote in the column. She said she loved Miller “as a brother” and lacked perspective at the time.

“I wanted to feel my workplace and my world were safe, untouched by the outside world — a privilege in and of itself, the privilege of ignoring what hasn't hurt you — and I claimed that safety at cost to someone else, someone very special,” she wrote, referring to Perrineau.

Dunham, 32, wrote that she will “always love” Perrineau, thinks of her daily and hopes they can have a relationship in the future.

“It's painful to realize that, while I thought I was selfaware, I had actually internalized the dominant male agenda that asks us to defend it no matter what, protect it no matter what, baby it no matter what,” she wrote.

She praised Perrineau's “bravery, openness, forgiveness, dignity and grace in the face of legal proceedings.”
