Earlier this week, famous Greek American actress Jennifer made a memorable appearance in “Jimmy Kimmel Live!” show and revealed a different aspect of her personality than the sweet and elegant Jennifer we all know and love.

Aniston and her former “Friends” co-star Lisa Kudrow took part in an original Celebrity Curse Off, a demanding battle of curses that requires imagination and a rich four-letter-word vocabulary.

Determined to win, Aniston used all the curse words she could think of and even resorted to her second language, Greek, for extra “ammunition.”

As you might have guessed, she chose to use the most frequent Greek curse and although the word “mal*kas” was a bit confusing for the host of the show, he decided to take her word for it and except it as a curse.
