First to get into the mix about whether Baby Kardashian West will be a boy or girl is Us Weekly which claims Kim and Kanye West are expecting a baby son!
A source told the mag: "Kanye loves Nori more than anything, but to make his world complete he wanted a little boy, an heir. He's overjoyed!"
But, not so fast, according to Kim!
She tweeted today: "So many rumours... we are not having twins, yes I am carrying my own baby lol & we have not told anyone the sex of our baby yet! Nothing is confirmed unless you hear it from me!"
Kim, 34, and Kanye, 38, are already parents to daughter North, who turns two this month.
They kept the gender of North a secret until a month before her birth, when it was revealed on an episode of Keeping Up With The Kardashians. Viewers saw Kim attending a doctor's appointment in LA with her family, and although Kanye wasn't present, Kim said that he'd be thrilled by the new news.
"I'm so excited we're having a girl!' she said. "Who doesn't want a girl? I think they're the best! I know that's what Kanye always wanted."
If Kim's second child is a boy, he'll have no shortage of male companions: her sister Kourtney, 35, is mum to sons Mason, five, and Reign, six months.
