The 32-year-old 'Keeping Up with the Kardashians' star, who gave birth to daughter North with West, thinks that if she marries in 2013, it might bring back luck to her family, reported Daily Star.
"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 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.
