The `Jersey Shore` star wants to have a family some day but seeing her best friend Nicole `Snooki` Polizzi deal with her pregnancy made her realise how much life has to change when caring for a baby. She told `Access Hollywood`: "[Snooki] handles it very well, but it did make me realise that you can`t be selfish anymore. "Nicole is preparing to give birth to a beautiful baby boy but she has to dedicate her life and her routine to him. "I want to be selfish just a little bit longer - [it] made me kind of put a chastity belt on. It gave me the itch to wait a while." Before she fell pregnant with fiance Jionni Lavelle`s baby, Snooki was renowned for her wild partying and JWoww is proud of how her friend has adjusted to a quieter lifestyle. She added: "She`s actually an amazing pregnant person." The friends appear together in a new reality TV show, `Snooki and JWoww` and Snooki thinks it will show people how "normal" their lives actually are. She said: "I definitely want to show everyone that it`s not all about partying and that I`m a normal person. "It will just show our day-to-day lives. We`re just going to be normal."
