Courtney Cox got a boob job in late 2011. While she hasn't come out and explicitly said it, there's no doubt that her breast size was increased by over a cup. She went from an A cup to a 32C. This side by side comparison shows Courtney Cox in 1995 and 2011. She had just come out of a relationship at the time and clearly wanted to show off a sexy new body. Dr. Ashkan Ghavami mentioned how this is a common occurrence, "It appears as though she has had an increase in breast volume as well as a change in shape. Plastic surgery after relationship changes is fairly common."
