Kim gave birth to her first child with rapper boyfriend Kanye West in July.
Even though Kanye has already popped the big question, she wants to wait, reports dailystar.co.uk.
"Kanye asked Kim to marry him straight after the birth of their baby daughter North West. He didn’t want any fuss, he just wanted to go and get hitched within the month," a source said.
Kim, who was married to baskteball player Kris Humphries for 72 days and went through a nasty divorce, feels her marriage to Kanye won't work out if they wed this year.
“But Kim is far too superstitious. She’s crazy and irrational about superstitions and is not having any of it," a source said.
“Kim thinks it’s bound to end in disaster if they get married in 2013 because she believes the number 13 is unlucky," the source added.
