It took them long enough!

Kourtney Kardashian has finally agreed to walk down the aisle with longtime boyfriend and baby daddy Scott Disick, Life & Style reports.

The mother-of-two has rejected his marriage proposals on numerous occasions before, but after both of Disick's parents died suddenly this year, she realized she and their children are all he has and relented.

    "Kourtney realized that she's all he has. It's made her see things differently. This is the perfect time for Scott and Kourtney to get married," a source told the mag.

The couple is eyeing family pal Joe Francis' Punta Mita, Mexico mansion as the wedding destination, and although they want to keep it low key with just close family and friends, they aren't sparing any expense! They plan to fly all the guests on private jets to the tune of $100,000!

The nuptials could take place any day now, considering the soon-to-be Mr. and Mrs. just held bachelor and bachelorette parties in NYC on February 22.

Kimmy K is none too thrilled about her older sister stealing her thunder, either!

    "There are rules about that kind of thing. If your sister gets engaged before you do, you don't get married before her!" a source close to Kim griped to the glossy.

All these happily ever afters just mean more cash for Kris Jenner!
