Kim and Kanye -- The Son Also Rises

Breaking News

North West is gonna have a little brother to taunt, because Kim Kardashian just spilled the beans.

Kim chose the appropriate day for the reveal on social media, saying to Kanye, "Precious moments like this when we were traveling on tour with you and what I live for," adding, "You're such a good daddy to North & you will be the best daddy to our new son too!"

We had heard it was a boy for a few weeks, but Kim chose to make it official late on Father's Day.

Presumably Caitlyn Jenner will be the child's grandfather ... at least if consistency rules. But you never know.
