Best Supporting Actress winner, Melissa Leo has made the first person in Oscars history to have dropped the F-bomb when accepting award.

She has been inviting criticisms for the self-promoting ads she had run in film trade papers before the actual ceremony Sunday night. But this attention was overshadowed when Oscars Best Supporting Actress winner, Melissa Leo had dropped the F-bomb while accepting her statue.

In her failure to compose herself, as if proving she has undermined herself as a strong contender for the award as people may have suspected from her self-promoting ads, Leo according to ContactMusic.com spoke nervously about how she had imagined herself taking the prize, adding she thought that it would be an easy task.

Not knowing what to say or where to look, the winner for the actress in the leading role for "The Fighter", even saw the audience in the mezzanine before she dropped the F-bomb.

"Yeah, I am kind of speechless; golly sakes, there's people up there too," Leo said, according to the Associated Press, then waved trembling at the mezzanine audience.

"When I watched Kate [Winslet win] two years ago, it looked so f---ing easy!," Leo exclaimed making her audience erupted into laughter from what seemed like a whole day of boredom even if the show had just began.

The F-word was subsequently bleeped for its international broadcast. After calming herself down, Leo was quick to apologize backstage.

"Those words, I apologise to anyone that they offend," she said, according to the Sidney Morning Herald. "There is a great deal of the English language that is in my vernacular."

Well, we all know, the damage has been done.
