Here's Jennifer Aniston on the set of Just Go With It. Jen has been wearing the skimpiest of outfits showing off her hot new body. Close friends reveal that Jen is obsessed with the way she looks and spends close to two hours in the gym. A source says, "She's scared of ageing and wants to be in her best form. It's also her way of telling Brad, 'look what you missed!'. We couldn't agree more.
