Kim's mum Kris also had some sweet words to say about her son-in-law. The 59-year-old shared a black and white image of Kanye on her Instagram account, writing: "Happy birthday to my son @kanyewest #KanyeWest!!!! You are such an amazing Daddy, husband, friend, son and brother… you are such a special part of my family and we feel so blessed.

"Thank you for sharing your passion, creativity and love with me each and every day. You are such an inspiration! Have the best day!!! #love #family #lovebug".

Kanye's birthday is not the only reason the couple have to celebrate this week. Kim recently announced that she and Kanye are expecting their second baby together.

The reality TV star revealed the happy news in a teaser for an upcoming episode of Keeping Up with the Kardashians. In the clip, Kim is seen receiving news that she's pregnant during an appointment with her doctor.

She then tells sister Khloe: "I just got the blood test back, and I am pregnant!"

The couple stepped out for the first time since their pregnancy announcement at the CFDA Fashion Awards in New York, where Kim revealed how grateful she was to be expecting a sibling for her daughter North West.

"It's a very different type of pregnancy from my first one, but I'm so grateful to be pregnant when we didn't even think it was going to happen for us," she told Us Weekly. "I don’t care how sick I am."
