It has been confirmed by Miss California officials that the pageant paid for her breast implants. Plastic surgery procedures had become very common in pageants and Miss USA is not the exception.
Kristen Dalton, from North Carolina won Miss USA 2009, but controversial Miss California, Carrie Prejean has been in the public eye for weeks after the show because of her point of view opposing gay marriage.
About Carrie's breast implants we think she choose an appropriate size for her body frame because bigger ones would look "too much" for her. We don't think that she got any other plastic surgery at the moment, but it doens't mean that she wouldn't in the future: for people who have gotten plastic surgery (like implants) and it went right, it may be easier to go for further procedures when they think they need it.
