A source close to the situation explained:
Kim Kardashian just got the most amazing birthday present of all time - an engagement ring!
Baby daddy Kanye West popped the question at San Francisco's AT&T Park, which he rented out for the occasion, and invited all of their family and friends for the special moment!
The story goes that her fam was already celebrating Kim's bday in San Fran when Kanye shocked the birthday girl with the proposal heard ’round the world!
How romantic! We're guessing they decided to make a home run shortly after! LOLz!
Congrats to the happy couple! If the proposal took over a stadium, we can't wait to see how big the wedding is!!
