Happy Birthday, Khloé Kardashian! The stunning E! star turns the big 3-0 today, and she has seriously never looked better! The youngest Kardashian sister knows how to flaunt her fabulous curves in fitted jeans and sexy dresses with thigh-baring slits. French Montana is one lucky guy! The beauty works extra hard with trainer Gunnar Peterson to maintain her banging body, doing plyometric push-ups, the sled, dead lifts, resistance bands and ab movements. It's certainly paying off, because Khloé always makes a memorable statement whether she's hitting the red carpet or out and about with her famous family!
