Talk about a happy birthday.
A rep for the reality star confirms the news that the couple are engaged.
West, 36, appeared on the same night at the Hollywood Film Awards in Beverly Hills, making reference to a quick commute from San Francisco but saying nothing about a wedding proposal.
For the big moment, West hired an orchestra to play for Kardashian, while a large screen flashed the words “PLEEEASE MARRY MEEE!!!!”
The rapper and the reality starlet, who first went public with their relationship in 2012, are parents to 4-month-old daughter North.
This will be the third marriage for Kardashian, who filed for divorce from basketball star Kris Humphries in 2011 after just 72 days as husband and wife. Their long-running divorce battle finally ended last June.
Her first marriage to music producer Damon Thomas ended in divorce in 2004.
