Three years after becoming the first Spanish-born actress to win a Best Supporting Actress Oscar, Penelope Cruz returned to the Academy Awards red carpet, dazzling at Sunday's 84th annual show in a custom Armani Prive organza gown.

A presenter at Sunday's awards fete, Cruz, 37, accessorized her off-the-shoulder frock with Chopard jewels and a pinned undo.

Cruz's Sunday outing comes just over one year after she welcomed son Leo with husband Javier Bardem.

How did the Spanish stunner snap back into shape so quickly after welcoming her adorable little one? "I love ballet and it's a little boring for me to go to the gym because I'm used to the dancing discipline," Cruz told The Daily Mirror. "It's really hard but much more fun."
