Olivia Wilde Posts Salad Dressing Recipe From Famed Ephron Cheating Novel

Olivia Wilde appeared to respond to the drama surrounding her and ex-fiancé Jason Sudeikis by sharing an excerpt from Nora Ephron's book Heartburn.

On Tuesday, the Don't Worry Darling director, 38, shared a page from the autobiographical novel, which featured a salad recipe, to her Instagram Story.

The note followed a Daily Mail report that detailed the downfall of the A-listers' relationship, based on shocking allegations from their former nanny.

In the article, the unidentified nanny claimed Wilde—who has children Otis, 8, and Daisy, 6, with Sudeikis—walked out on the family to pursue a relationship with Don't Worry Darling star Harry Styles.

The nanny recalled one alleged incident at the couple's home when Wilde left to have dinner with the One Direction alum, 28, bringing her "special" salad dressing with her. Sudeikis, 47, was apparently so upset that he "went outside and lay under her car so she wouldn't leave."

The post on Wilde's Instagram Story came after Twitter exploded with people wanting to know what was in the salad dressing that made it so spectacular.

The excerpt from Ephron's book read: "I came home and started dinner. I made a bouillabaisse, and crème brulée, and in between there was a salad. I taught Mark to make the vinaigrette.

"Mix two tablespoons Grey Poupon mustard with 2 tablespoons good red wine vinegar. Then, whisking constantly with a fork, slowly add 6 tablespoons olive oil, until the vinaigrette is thick and creamy; this makes a very strong vinaigrette that's perfect for salad greens like arugula and watercress and endive."

Wilde and Sudeikis have since denied all allegations, including claims they fired the nanny without severance pay.

"As parents, it is incredibly upsetting to learn that a former nanny of our two young children would choose to make such false and scurrilous accusations about us publicly," the pair said in a rare joint statement obtained by Newsweek.

"Her now 18 month long campaign of harassing us, as well as loved ones, close friends and colleagues, has reached its unfortunate apex. We will continue to focus on raising and protecting our children with the sincere hope that she will now choose to leave our family alone."

Ephron, a journalist and screenwriter who died in 2012, based Heartburn on her marriage and divorce from second husband, Carl Bernstein, the investigative reporter best known for exposing the Watergate scandal with Bob Woodward.

In 1979, Bernstein had an affair with Margaret Jay, the daughter of former British prime minister James Callaghan. Heartburn was published in 1983.

"Seven months into her pregnancy, Rachel discovers that her husband is in love with another woman," reads a synopsis of the book, per Amazon. "The fact that this woman has a 'neck as long as an arm and a nose as long as a thumb' is no consolation. Food sometimes is, though, since Rachel is a cookery writer, and between trying to win Mark back and wishing him dead, she offers us some of her favorite recipes.

"Heartburn is a roller coaster of love, betrayal, loss and—most satisfyingly—revenge."

The book was turned into a movie in 1986 with Meryl Streep and Jack Nicholson in the lead roles.
