More from TMZ:

Nora Ephron — the legendary Hollywood writer who penned the screenplays for “Sleepless in Seattle” and “When Harry Met Sally” — is gravely ill … family members are telling close friends.

The nature of her illness is unclear … however there are reports she is suffering from cancer and is not expected to make it through the night.

There is speculation that Nora has already passed away — we’re told that’s not true … but there is little hope she will recover from her current condition.

71-year-old Ephron was nominated for 3 Academy Awards in her illustrious Hollywood career … and was widely considered one of the most powerful women in the entertainment industry.

Ms. Ephron is a writer, director and producer. She has written novels, including “Heartburn,” and screenplays, including “Silkwood” and “When Harry Met Sally.” She also directed and co-wrote “Sleepless in Seattle.”

She is also a wife and mother; our prayers are also with her husband and children.

Update: Nora Ephron’s agent is confirming the news: She’s gravely ill with leukemia.

Prayers and thoughts going out from around the Twittersphere:

More from CBS:

NEW YORK – Nora Ephron, the Oscar-nominated filmmaker and director behind such hits as “When Harry Met Sally” and “Sleepless in Seattle,” has passed away, CBS News has learned.

Nicholas Latimer of Alfred A. Knopf confirmed to the Associated Press earlier Tuesday her deteriorating condition hours after celebrity columnist and friend Liz Smith published what appeared to be a memorial for the writer.

Smith told The Associated Press that she had spoken to Ephron’s son Jacob on Tuesday morning and was told that Ephron was dying. She said when she heard that funeral plans had been arranged, she published the column on the website Women on the Web.

“I was confused because I was told to come to the funeral on Thursday,” Smith said. “It’s bad enough.”

Twitter users, including journalists, authors and celebrities, express their condolences.

More from The New York Times:

In addition to her son Jacob Bernstein, a journalist who writes frequently for the Styles section of The Times, Ms. Ephron is survived by Mr. Pileggi; another son, Max, a musician; and her sisters Delia Ephron; Amy Ephron, who is also a screenwriter; and Hallie Ephron, a journalist and novelist.

In person Ms. Ephron — small and fine-boned with high cheeks and a toothy smile — had the same understated, though no less witty, style that she brought to the page.

“Sitting at a table with Nora was like being in a Nora Ephron movie,” Ms. Quinn said. “She was brilliant and funny.”

She was also fussy about her hair and made a point of having it professionally blow-dried twice a week. “It’s cheaper by far than psychoanalysis and much more uplifting,” Ms. Ephron said.

Another friend, Robert Gottlieb, who had edited her books since the 1970s, called Ms. Ephron’s death “terrible for her readers and her movie audience and her colleagues.” But “the private Nora was even more remarkable,” he added, saying she was “always there for you with a full heart plus the crucial dose of the reality principle.”

Read the whole thing.

Many Twitter users are remembering their favorite Ephron writings.

Her lively, bright and witty earthly voice has been silenced, sadly. But her words will continue to be read and heard for eternity. What a legacy, Ms. Ephron.
