In his Yeezus concert in California last Tuesday, rapper Kanye West expressed his pride for Kim Kardashian through a song. For the first time in public, West called the reality TV actress "my fiancée".  

After having their first baby, North, last month, the couple has decided to finally seal their love. Just in time for Kardashian's 33rd birthday, the rapper proposed to the 'Keeping Up with the Kardashians' star by presenting a 15-carat diamond ring exclusively created by Lorraine Schwartz. To show his determination to get Karadshian's "Yes", the 'Blood on the Leaves' singer knelt at the AT&T baseball park in San Francisco, California. He hired an orchestra with 50 members and also arranged a fireworks display to complement his proposal.

Just a day after the engagement, West performed his song 'Bound 2' with a special dedication:  "You know what song this is, right? I want to sing this song to the birthday girl that's back there right now, my fiancee."

The rapper similarly talked about how his relationship with Kardashian gave him another chance in life. Kardashian, who watched the concert with her mother, was smiling all throughout the performance of his husband-to-be. 

"If you came with somebody that you love tonight, hold on so tight. What I'm trying to say is it's hard to find you," gushed West. After the magical proposal, Kardashian's family members have been quick to share their congratulatory messages.

In a tweet, Khloe Kardashian Odom expressed her happiness for her half-sister: "Wow!!!!! Am I dreaming??!?! Tears of JOY!!!!!!! Wow!!!!!!" 

"I am so happy for both of my kids, Kim and Kanye. A match made in heaven," said the family's matriarch, Kris Jenner, in a separate interview with E! News.

No official wedding date has been confirmed yet although the couple is now renovating an $11 million-worth Be lAir mansion that will serve as their love nest.
