Cruz, Penn to present at Oscars

Last year's winners sign on for March 7 ceremony

Last year's three living acting Oscar winners -- Sean Penn, Kate Winslet and Penelope Cruz -- have all booked return visits to the 82nd Annual Academy Awards, where they will appear as presenters.

Cruz, who took home the supporting actress Oscar last year for "Vicky Cristina Barcelona," has an added reason to show up since she's nominated this year in the same category for playing the seductive mistress in "Nine."

Penn earned the best actor Oscar last year for "Milk," while Winslet was crowned best actress for "The Reader."

Last year's fourth acting trophy went to Heath Ledger posthumously for his performance as The Joker in "The Dark Knight."

The Oscars will be broadcast live by ABC from the Kodak Theater in Hollywood on March 7.
