Courteney Cox CCox092508_05_X17.jpg

Friends Courteney Cox and Jennifer Aniston support each other through everything: marriages, having kids (well, Courteney, anyway), divorce, break-ups and more break-ups!

But when it comes to supporting her BFF on her spokesmodeling career for Smartwater, that's where Courteney draws the line!

While Jen only drinks the stuff they pay her to schill, Courteney's drink of choice is Arrowhead.
