Kim Kardashian gushes that Kanye West will be 'best daddy' to son they're expecting

It's a boy for Kim and Kanye: Littlest West rumored to be due in December

Kim Kardashian and Kanye West are expecting a son, the reality star announced Sunday in the context of Father's Day praise to her husband. 

"You're such a good daddy to North & you will be the best daddy to our new son too!," she tweeted late on the holiday, including emojis of a mom, dad, girl and boy. 

In addition to posting a cute picture of West reading to North, the "Keeping Up With the Kardashians" star also wished a happy Father's Day to the late Robert Kardashian, who died in September 2003.

"Been a while since you've been gone but the memories run so deep they'll last 4ever," she wrote, posting a couple of childhood pictures. She didn't acknowledge stepfather Caitlyn Jenner.

The new baby — to be named later, although not to be named South West — is rumored to have a December due date. The sly announcement that a boy was on the way confirmed rumors that popped up about two weeks ago, shortly after it went public on "KUWTK" that Kim was pregnant again.

"I don't like South West, though, because that's like — you know, North will always, you know, be better. ... And be more — she has a better direction," the 34-year-old said a little over a week ago when she appeared on NPR's "Wait Wait ... Don't Tell Me" and set off a barrage of loathing from the public radio network's we're-better-than-that listenership.

"I mean, everyone keeps on saying South, and I think it's so stupid. ... Stupidest thing ever and just ridiculous," she added.

North West, the big sis-to-be, was born June 13, 2013. The fam recently headed to Disneyland to celebrate her second birthday.
