@LondonWolf - oh calm down. I was relaying the only explanation I had read in the media. I also said I don't remember seeing the film so clearly not my interpretation 
I also acknowledged further down that stuntbubbles had a much better interpretation (though again I can't vouch for the veracity of that before you accuse me of making things up again).
From the rhythm of the joke – Javier Bardem,
nominated; Penelope Cruz, nominated; Will Smith, nominated; Jada Pinkett-Smith, GI Jane 2, I.e. not nominated and, lol, probably in a shit sequel to a shit film – I interpreted it as less about her looks and more a career dig, but velvet glove with the “love you, can’t wait to see it”, to get away with it.
