As for the breast implants: We'll see how the sweet young things feel about their overly generous endowments when they are 60 years old and have dents in their shoulders from holding them up.
My guess the reason Brit made this announcement is that she couldn't not show any longer.
Speaking of implants: The only few seconds of the Miss USA pageant I saw the other night were when the reigning Miss USA showed up with her plastic bosoms exposed for all to see. I guess she always wants to be prepared in case a volleyball game (or two) breaks out.
