Kanye West and Kim Kardashian
's motto for her wedding to fiancé Kanye West
is simple: leave it up to Kanye.
The newly engaged
reality star flashed her 15-carat sparkler
on the red carpet at her 33rd birthday party at Tao Las Vegas Friday night, but said that little-to-nothing has been discussed about the wedding or even how long of an engagement she and West will have.
"We honestly haven't had a moment to talk about it or even breathe, so we haven't really talked about it, but whatever he wants," she told PEOPLE, adding that the only sure thing is that stepdad Bruce Jenner will walk her down the aisle.
Donning a white lace dress she purchased in Paris while pregnant, Kardashian said the proposal was an "absolute, complete surprise." Even her family – who had gathered at San Francisco's AT&T Park – assumed it was for a surprise birthday party.
"I was shaking so much, shaking the entire time," she said. "Like, 'Is this really happening?' It was like an out-of-body experience."
Her whirlwind week continued, and she got to celebrate her birthday in Vegas.
Following West's concert at MGM Grand, Kardashian and West – along with sisters Kourtney Kardashian
and Khloé Kardashian Odom
and mom Kris Jenner – headed to Tao to celebrate her birthday. Once inside the packed club, she was greeted with an oversize cake, champagne and a litany of West songs spun by DJ Five.
