And while Kim, 34, recently blasted rumours they had planned to call their unborn son South, it's not too far away on the compass...
According to the Daily Mail, a friend has confirmed Kimye will be calling their second child Easton.
A family friend told the newspaper that the couple have settled on the name so that personalised items for his nursery can be made.
And early rumours about daughter North's name turned out to be true...
The insider says: "Easton is the chosen name. It's confirmed that the baby boy will be called Easton.
"Kourtney told a few girls at a Hidden Hills pool party last weekend that Kanye's favourite name by far is Easton, a name Kim wasn't hot on at first because Kanye liked simply East.
"But Kim came up with Easton and, for them, history was made."
Kim has already been very vocal about disliking the name South, saying it would be "stupid".
After announcing the pregnancy in June, she said: "I don't like South West. North will always be better and have a better direction. I wouldn't do that.
"I don't think we will go with another direction. Everyone keeps on saying South and I think it's so stupid. The stupidest thing ever and just ridiculous."
Kimye's second child is due in December, and will be a new playdate for older sister North, two.
Kim and rapper hubby Kayne West, 38, announced they were expecting their second child after a not-so-private fertility battle.
She revealed she was pregnant again in a teaser following the mid-season finale of Keeping Up With The Kardashians.
