Kanye popped the question on Kim's birthday

Kim Kardashian has been showing off her whopping engagement ring.

The reality star is set to marry Kanye West, 36, after the rapper proposed to her in a very lavish fashion on her 33rd birthday.

Kanye hired out San Francisco’s AT&T Park baseball stadium on Monday and got down on one knee to proffer a 15-carat diamond rock created by jewellery designer Lorraine Schwartz.

After agreeing to become Mrs West, Kim excitedly shared a snap of the stunning ring on Instagram.

YES!!!‘ she captioned the picture, where the message ‘PLEEEASE MARRY MEEE!!!‘ is seen on the stadium’s jumbo screen in front of her.

Kanye was involved in designing the sparkler and made sure it was completely perfect for his future wife, with a rep for Lorraine Schwartz saying that the ‘flawless’ rock is ‘the best diamond there is’.

As well as flashing her new piece of bling, Kim has spoken of her joy about the happy news.

‘Last night was truly magical!!!’ the new mum, who gave birth to baby North West in June, tells E! News.

‘I am the luckiest girl in the world! I get to marry my best friend!’
