Kourtney Kardashian is the mother to two beautiful kids, Mason and Penelope.
They are her life, and we bet she wants to see them grow into adults so she can eventually have a bunch of grandkids running around!
By staying fit and eating right, of course!
She definitely does both, as we can tell from her newest bikini pics!
She was celebrating her 35th birthday with her man Scott Disick in Los Cabos, Mexico. They were there with both the little ones — and damn was Kourtney lookin' fine! She was all kinds of fit in her tiny two piece.
Her body looks great for any woman, let alone a mother of two!
Way to keep up that fitness, Kourtney! Happy Birthday!
