Khloe Kardashian's baby bump was on full display in a Game of Thrones costume for Halloween, and she's never looked sexier!

Dressing up as Daenerys Targaryen and Khal Drogo, Khloe and her boyfriend Tristan Thompson wore custom outfits by Bryan Hearns. Though the soon-to-be parents haven't put a ring on it yet, they couldn't have looked more in love.

Khloe was spotted in NYC last week while filming Keeping Up With The Kardashians. Wearing a low-cut top and matching coat, the pregnant star proved pregnancy can certainly be posh.

While Khloe is reportedly about five months along in her pregnancy, she certainly didn't look it in these photos. She's clearly doing what she can to stay in shape during her pregnancy.

So what's her secret? For starters, she's trying to eat as healthily as she can. Of course, she does have a few cravings.

Sources also told Us Weekly that Khloe Kardashian is staying fit by eating "smaller meals throughout the day." She also continues to work out, with an emphasis on "more cardio" and "less intensive" workouts.

Of course, it's inevitable that Khloe's stomach will get bigger as she gets closer to her due date. But after struggling with body image for years, she's learned to celebrate her curves.

"My weight fluctuates all the time and I love that at any size I feel comfortable," she said at a Good American appearance in California. "When I was bigger and wore bigger clothes I looked even bigger. I love embracing my curves no matter what size I am."
