Kim Kardashian almost missed engagement surprise after falling ill

Reality star Kim Kardashian almost missed out on her surprise engagement after falling ill with a bout of stomach flu.

Rapper Kanye West popped the question to the mother of his baby daughter with a 15-carat Lorraine Schwartz ring on her 33rd birthday on 21 October (13), taking over the San Francisco Giants' baseball stadium for the grand gesture.

Kardashian had no idea about the proposal and assumed West was taking her to the sports arena for a birthday dinner, and now her sister Khloe reveals Kim actually wanted to stay home that night after feeling sick.

Khloe Kardashian says, ''She was talking to me earlier that day because she wasn't feeling well. 'She was like, 'I'm so sick, I don't want to go anywhere. I just wish I could lay in bed,' and I thought, 'If she doesn't get on that plane (to San Francisco) we're all screwed'."

However, the plan went off without a hitch and the couple will reportedly tie the knot next summer (14).
