They're engaged! Kanye West proposes to Kim Kardashian on her birthday

But it appears Kanye West couldn't wait any longer to make their relationship official.

Kanye was in Los Angeles earlier in the day at the Hollywood Film Awards, and it was therefore unclear whether he planned to spend Kim's birthday with her. She was allegedly seen boarding a private jet that afternoon with her family in Los Angeles. Kanye flew in from San Francisco Monday to present director Steve McQueen with a special honor award at the ceremony, and it appears he must have flown back to the Bay Area city straight afterwards to see the mother of his child. Their upcoming nuptials with be Kim's third marriage, and Kanye's first.
Kanye was seen speaking onstage during the ceremony, where he presented a special honor award to 12 Years A Slave director Steve McQueen. Kanye allegedly joked during his speech that he was 'reading from the teleprompter' to keep himself in check. The pair were then seen kicking back with a drink in a lounge backstage. Meanwhile, reports emerged Monday that Kim and Kanye are reportedly planning to have another baby. The pair only welcomed their first born, daughter North, into the world in June, but are already considering extending their family as they are concerned time may not be on their side when it comes to conceiving. A source told RadarOnline: 'They are discussing having another baby right away. It's serious. [Kim] is well aware that she's getting older, and that if she wants to have a bigger family, then she needs to get it done.'
