The former Olympic athlete was unaware his step-daughter was going to be proposed to by her boyfriend Kanye West at the AT&T Park stadium in San Francisco on Monday night (21.10.13), and only found out the good news once the lavish event had taken place.
Bruce - who recently split from Kim's mother Kris Jenner after 22 years of marriage - reportedly disapproved of the 33-year-old reality star striking up a relationship with Kanye so soon after her marriage to ex-husband Kris Humphries ended in 2011.
However, Kim - who has four-month-old daughter North with Kanye - phoned Bruce almost ''immediately'' after the 36-year-old rapper popped the question as she ''considers him [Bruce] to be her father,'' according to TMZ.
Meanwhile, brunette beauty feels like the ''luckiest girl in the world'' to be marrying her beau and believes the proposal, which Kanye organised himself, was truly ''magical''.
The 'Black Skinhead' hitmaker rented out the baseball field for $35,000 and hired a 50-member orchestra for $50,000, who performed his hit 'Knock You Down' and Lana Del Ray's 'Young & Beautiful,', before fireworks lit up the sky and the words ''PLEEEASE MARRY MEEE!!!'' flashed up on the scoreboard.
He also booked San Francisco's top caterer for the event and helped to design her engagement ring with Lorraine Schwartz, before secretly flying Kim's family and friends to the venue.
