According to People Magazine the New Jersey Nets star asked Kardashian to marry him by surprising her at her Beverly Hills home on May 18. Kim is also sporting a 20.5 carat diamond engagement ring.

Kardashian, 30, and Humphries, 26, seemed to be priming fans for a big announcement for weeks, hinting on Twitter about family gatherings. They were recently spotted shopping for engagement rings and she was photographed frequently at his basketball games.

Kim's sister is also married to a basketball star. After a whirlwind romance, Khloe married Lakers baller Lamar Odom in 2009. He gave her a nine-carat engagement ring, which now pales in comparison to her sister's ring which is estimated to be worth about 2 million dollars.
