It was definitely a memorable birthday for Kim Kardashian! On the reality star's 33rd birthday, boyfriend Kanye West popped the question at San Francisco's AT&T Park, which he rented out for the special occasion. Before the proposal, West asked his future mother-in-law, Kris Jenner, for her daughter's hand in marriage. The rapper proposed with a 15-carat diamond ring by Lorriane Schwartz, as the field's giant screen flashed, "PLEEEASE MARRY ME!!!" But that's not all. A 50-piece orchestra played Lana Del Rey's "Young and Beautiful," followed by Keri Hilson, Ne-Yo and Kanye's "Knock You Down." Fireworks then went off in celebration. The new parents began dating in 2012 and welcomed their first daughter, North West, in June.
