"It won't be a huge wedding," a source toldthe magazine. "Around 150 people."
The source is consistent with what Kardashian had told Ryan Seacrest on his radio show late last month, that she and the rapper had a change of heart and are planning a "super, super-small intimate" wedding.
Kardashian recently told People she hasn't picked out her perfect dress to walk down the aisle in yet.
"[I've shopped] a little bit, but I really need a good sit down to plan it all out," the 33-year-old reality TV star explained.
"I'm just really excited for this year. So many exciting things are happening in my life, and I feel so much good energy. It's just going to be the best!"
A family insider also reportedly added, "Kim can't wait to marry Kanye."
Kardashian had divorced music producer Damon Thomas in 2004 and NBA basketball player Kris Humphries in 2011.
Kardashian began dating West, 36, shortly after her split from Humphries and the couple welcomed their daughter North "Nori" West into the world in June 2013. Kardashian and West then got engaged on the reality TV star's birthday in October of last year.
