Jen's Date ... With Courteney!

While Brad Pitt and Angelina Jolie were getting handsy at the Invictus premiere, Jennifer Aniston was on a date of her own at the Sunset Towers -- with her best Friend Courteney Cox!

Now, before you get all "awww, how sad the spinster can't find a date," just look at how happy Jen looks in these pix. Maybe she's finally come to the conclusion that she doesn't need a man!

Or maybe she's hiding one in the back seat?
