Girlfriend is looking so bomb lately!

Khloe Kardashian caught a flight out of LAX this morning, and we couldn't help but notice that her boobs seem to be getting perkier the more weight she loses. The reality star donned a nude bodysuit with jeans and a fedora, and she's never looked better.

Her new romance with NBA star Tristan Thompson is certainly putting a pep in her step, too! Although a source tells E! the pair are "not too serious" yet, they "have gotten much closer" and it seems to be headed in the serious relationship direction. "She hasn't had this much fun since she was with James [Harden]," the source revealed.

Khlo's love of basketball players isn't going over too well with her ex Lamar Odom, though. "[Lamar Odom] wouldn’t be so pissed about Khloe’s dating life if she dated outside the NBA. He feels like she’s hooking up with dudes in the league to f**k with him and his mental state. When he saw pics of them together he was hurt," a source dished to Hollywood Life.

Her new dude is a lucky man! She's officially the hottest Kardashian. All hail Queen Koko!
