Jenni 'JWoww' Farley is too "selfish" to have children yet.

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 realize 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 realize 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."
