Is it possible that seeing Kim Kardashian in this white one-piece had love Kanye West imagining her … in a white dress? Less than one week after her sexy selife, the new parents are engaged!

West popped the question Monday night (on Kim’s 33rd birthday!) in front of family and friends at San Francisco’s AT&T Park. And he brought a very special birthday present with him: a 15-carat square diamond ring by Kardashian-family-loved jeweler Lorraine Schwartz, E! News reports. (Schwartz also designed Kardashian’s previous engagement ring from ex-husband Kris Humphries, which recently sold for $749,000 at a Christie’s New York Magnificent Jewels auction.)

And her new diamond (or should we say “mini planet”) is definitely one that deserves a proposal in a stadium over a big screen. Kardashian made sure she snapped a selfie to remember the magical moment, posting the above photo of the sparkler — with the caption “YES!!!” — in front of West’s sweet ballpark message: “Please Marry Me!”

Her hairstylist Clyde Haygood also shared a photo of the bauble on Instagram (see below), and basically, the massive rectangular diamond is the size of baby Nori’s head.

Kardashian looks totally shocked in the endearing photo, as West smiles big behind her. And sister Khloé Kardashian Odom must have been there for the celebration, posting the following Tweet:

What do you think of Kardashian’s ring? Do you like it better than her last one? Sound off below!
