Oscar winner Melissa Leo has apologised for any offence caused by her Best Supporting Actress acceptance speech after letting slip the F-word during Sunday's (27Feb11) live telecast.
The 50-year-old star was one of the first honorees of the night, claiming the prize for her gritty role as tough-talking Alice Ward, mother of Boston, Massachusetts boxing legends Micky Ward and DICk Ecklund, in The Fighter.
But the nervous actress, who admitted she was "shaking in my boots", accidentally turned the air blue as she marvelled at the packed audience at Hollywood's Kodak Theatre.
She gasped, "When I watched Kate (Winslet, 2008 Oscar winner) two (sic) years ago it looked so f**king easy!"
Leo's blunder prompted her fellow Oscar honouree and The Fighter co-star Christian Bale to joke about the mishap as he collected gold for Best Actor in a Supporting Role.
Referring to his infamous rant on the set of Terminator Salvation, he laughed, "Melissa, I'm not gonna drop the F-bomb, I've done that plenty before!"
However, Leo made an effort to make amends for the slip-up after she came off stage at the prestigious ceremony.
Speaking to reporters backstage, she said, "Those words - I apologise to anyone if they offend. There's a great deal of the English language that is in my vernacular. I really don't mean to offend, and probably a very inappropriate place to use that particular word."
Leo wasn't the only The Fighter star celebrating at the 83rd Annual Academy Awards - Christian Bale walked away with the Best Supporting Actor accolade.
