Kim Kardashian Sends a Sweet Birthday Message to Kanye West

The reality TV start has been sharing details of their morning together.

"Happy Birthday 2my best friend in the entire world! U R the most amazing husband &dad! U inspire me every single day," she tweeted. "You make all of your dreams reality & it's fascinating to be by your side & watching it all happen! You have a heart of gold!"

Kardashian, 34, and West have had a lot to celebrate recently. A few days ago, the reality TV star announced that they're expecting their second baby. (Their eldest, North, turns two next week.) And while Kardashian teased that her husband's birthday will be "major," this morning was more low-key for the famous couple.

"Not sure why Kanye & I are up so early but we're eating cereal & I'm showing him all of your sweet birthday messages!" Kardashian wrote on Twitter.
