Renowned actress Jane Fonda joined fellow Hollywood veteran Diane Keaton Thursday, as she had a slip of the tongue on air and treated millions of NBC viewers to a bit of slang.

Academy Award-winning actress Jane Fonda was a guest on NBC’s “Today” show on Thursday, together with “The Vagina Monologues” writer Eve Ensler, when she temporarily shocked her audience – and even more visibly, host Meredith Vieira.

The 70-year-old thespian was explaining how it had come about that she performed in the play when a vulgar version of the word “vagina” slipped, unintentionally. She was only specifying the title of her segment in the play.

“I live in Georgia, okay,” Fonda said as she explained while she had initially tuned down the role in the play. “I was asked to do a monologue called ‘C---.’ I said, ‘I don't think so. I've got enough problems,’” she continued, appearing quite unaware of the language she had just used.

Vieira however seemed painfully aware.

Fonda further explained: “Then I came to New York and saw it and it changed my life. I was theoretically a feminist but I didn't always live it behind closed doors. When I saw ‘The Vagina Monologues,’ I'd never laughed or cried so hard in the theatre.

Vieira issued an on-air apology after the segment, telling the audience that Fonda “inadvertently said a word from the play that you don't say on television.”

“She apologizes and so do we,” the host continued. “We would do nothing to offend the audience.”

Thursday night Jane Fonda performed in the play on the occasion of the 10th anniversary of V-Day, the global movement to end violence against women and girls. It was founded by Eve Ensler on February 14, 1998 at the first benefit of her award winning play at the Hammerstein Ballroom in New York City.

Her non-profit group has raised over $50 million for local anti violence groups, the official website informs, with events taking place in over 120 countries to date and thousands more planned during the upcoming anniversary year.

A two-day anniversary is scheduled for April 11-12 in new Orleans, with Salma Hayek, Oprah Winfrey, Jane Fonda, Glenn Close, Julia Stiles, Sally Field, Marisa Tomei, Rosario Dawson, and others participating.

Fonda’s publicist said Thursday that the actress did not mean for her use of the X-rated word to be “shocking.”

“She was just quoting the title of her scene in ‘The Vagina Monologues,’” publicist Pat Kingsley said. “She didn't come up with the word. She certainly meant no disrespect.”

It was only a month ago that Diane Keaton admiringly told host Diane Sawyer of ABC’s “Good Morning America” that she wished she had lips like hers, because “then I wouldn't have worked on my f------ personality - excuse me - my personality.”

Keaton and Sawyer laughed, the actress apologized for the “slip-up” and Sawyer replied that her mother would wash her mouth with soap.

As “Good Morning America” is not on time delay, the word went freely on the air. ABC News senior vice president Jeffrey Schneider said the network bleeped the word for the Central, Mountain and Pacific time zone feeds and regretted the incident. “It was obviously unfortunate, and we were quick to correct it for subsequent feeds,” he said at the time.
