Nicole 'Snooki' Polizzi worries about her son walking in on her having sex.

The 27-year-old reality star - who has children Lorenzo, 16 months, and Giovanna, three months, with husband Jionni LaValle - always takes care to be quiet during lovemaking and says she and her spouse always wait until night time before getting intimate as they don't want to be intruded on.

She wrote on her website: '' We still have a sex life, but I just started birth control so I'm waiting for it to kick in before we do it again. I don't make any loud noises. We do it at night when the kids are sleeping because Lorenzo will walk in and just stare at us.''

While the former 'Jersey Shore' star has been happy to share her births and relationship with Jionni on screen, if the couple were to split, she insists she would never allow the demise of her marriage to be broadcast - though she claims her spouse wouldn't ''dare'' leave her.

She also said: If anything bad happens to me and Jionni, we are not taping it. ''I don't like negative energy. I love everything positive and butterflies... and zombies. I'll break Jionni's knee caps and kill him if he tries to leave me. He knows I'm crazy. I'm up his ass all the time.''
