Diane Keaton was in good spirits early Tuesday on the set of “Good Morning America” when she surprised viewers with a lively commentary including the f-word.

Renowned actress Diane Keaton was on the set of ABC’s “Good Morning America” to promote her new movie, “Mad Money,” when her attention turned to her host’s plump lips and she had her little slip of the tongue.

“I'd like to have lips like that,” the actress told Diane Sawyer. “Then I wouldn't have worked on my f------ personality - excuse me - my personality. If I had lips like yours, I'd be better off. My life would be better. I would be married. I have these thin lips.”

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, as quoted by the Hollywood Reporter.

Both Keaton and Sawyer laughed at the actress’s use of the expletive. The four-time Oscar-nominee, who won in 1977 for the title role of the Woody Allen-directed “Annie Hall” and who is known for her frank manner, apologized for the “slip-up” and Sawyer replied that her mother would wash her mouth with soap.

“My mother is going to work on your personality - with soap in your mouth, is what she's going to do,” she said.

“Mad Money” is Keaton’s most recent film, a comedy directed by Callie Khouri (Academy Award for Best Screenplay Written Directly for the Screen for “Thelma and Louise”). Keaton and co-stars Queen Latifah and Katie Holmes portray three women who form an unlikely friendship and decide to rob the Federal Reserve Bank. The film is set for release Friday, Jan. 18.

The Federal Communications Commission may not take action against ABC stations that aired “Good Morning America” on Tuesday, according to the Hollywood Reporter, after the regulator’s policy on “fleeting references” was dismissed by a federal appeals court in New York last year.

Under current law and commission policy, broadcasters can be fined up to $325,000 per indecent incident for each station, the same source added.
