( CNN ) -- For Kim Kardashian , the third engagement really is the charm . The 33-year-old reality star has gushed that the father of her child and now-fiancÃ© , Kanye West , pulled off a proposal this week that swept her off her feet . `` I am the luckiest girl in the world ! '' Kardashian said to E ! , which airs her family 's reality series , `` Keeping Up with the Kardashians . '' `` I get to marry my best friend ! '' West and Kardashian have known each other for years , as West told Kardashian matriach Kris Jenner on her talk show in August , and for the Grammy-winning rapper it was love at first sight . `` I was in love with her before I even got to talk to her , '' West , 36 , said . `` Being in the limelight , you have to have a match , or someone that 's equally yoked . It 's difficult , because there 's people that you would date who would try to date you to maybe be more famous , or people who would want you to be less famous than you were , and just not accept who you are in life . And when I would be on the phone with ( Kim ) , even at my lowest moments , she 'd give me energy and remind me of who I was . '' After dating publicly for a little over a year and welcoming their first child together , daughter North , in June , West popped the question on Kardashian 's 33rd birthday Monday . The artist set up an elaborate surprise at San Francisco 's AT & T Park , which he rented out for the proposal and filled with Kardashian 's close friends and family members . Kardashian 's mom knew what 'Ye was up to , as he 'd asked her for her blessing . So on Monday , the artist got down on one knee and proposed as his question flashed on the arena 's jumbotron : `` PLEEEASE MARRY MEEE ! ! ! '' And that was n't all : a 50-piece orchestra played Lana Del Rey 's `` Young and Beautiful '' followed by West 's own song with Keri Hilson , `` Knock You Down , '' with the whole extravaganza being topped off with fireworks . Accepting West 's 15-carat Lorraine Schwartz sparkler , Kardashian responded to his proposal with an enthusiastic `` YES ! ! ! ''
