Kanye West's on stage announcement that Kim Kardashian is pregnant was a total shock -- to Kim Kardashian ... TMZ has learned.
Sources close to Kim, who were at the concert, tell us Kim had "no idea" Kanye was going to tell the world she's knocked up. We're told she and Kanye had not discussed announcing it -- and, in fact, had planned to say nothing until she started showing.
According to our sources, Kanye was moved to blab on stage because Kim's BFF and her mom were at the show -- along with several of Kanye's family members.
Kim didn't seem to mind the surprise -- we're told she was crying tears of joy when Kanye revealed they're expecting, and was especially moved because he did it during one of her fave songs ... "Lost in the World."
Kim Kardashian isn't letting a little pregnancy slow down her New Year's Eve plans ... 'cause she will be partying -- as scheduled -- in Las Vegas tonight, TMZ has learned.
Kim has been set to ring in the new year at 1 Oak on the Vegas strip -- for some time now -- and we're told nothing's changed since Kanye West, unexpectedly, revealed their baby news.
The reason? $$$$
Sources tell us Kim will pull in six-figures for the appearance -- plus, boozing is a non-issue for KK ... who, we're told, has never been a big drinker anyway.
Also, our Kardashian sources say Kanye will be by Kim's side during the ritzy event -- it costs $125 just to stand in VIP -- and at least another $3,000 to get a table.
That's all before you buy champagne to toast Kimye's baby.
It’s true!! Kanye and I are expecting a baby. We feel so blessed and lucky and wish that in addition to both of our families, his mom and my dad could be here to celebrate this special time with us. Looking forward to great new beginnings in 2013 and to starting a family. Happy New Year!!! Xo
