Khloe Kardashian: This is how I hid my pregnancy for so long

Khloé Kardashian, master of disguise! The reality star, who is more than six months pregnant, kept her belly under wraps until December when she was ready to announce the news.

"I can't even believe I hid my bump for as long as I did, lol," wrote the Keeping Up With the Kardashians star in a Wednesday, January 17, post on her website. "It took a few styling sessions, serious strategy and a s–t-ton of courage, but it worked!"

The 33-year-old mom-be credits "billowy" outerwear for keeping eyes off her tummy. "I had already let the cat outta the bag when I wore this Whyte Studio coat," she explained, "But I've worn a million versions of it in the last six months. I almost never left home without one!"

Kardashian also opted for A-line silhouettes like the "super girly" eyelet number she wore to sister Kim Kardashian's baby shower in November. "Little did anyone know I had a bun in my oven too!" she shared. "A cinched waist with a flared, A-line hem is so $$$ for hiding small bulge. It It flows loosely at the exact right spot."

Us Weekly exclusively revealed in September that the Strong Looks Better Naked author is expecting her first child, a boy, with Cleveland Cavalier's player boyfriend Tristan Thompson. The baby will be born in Ohio so that Thompson can be by her side — and Khloe's mom, Kris Jenner, will join them in the delivery room.

While Jenner is a definite, Khloé isn't ruling out the possibility that her sisters will be on hand to watch baby Thompson make his big debut. "You know, I think I have to talk to Tristan about this. I know it's overwhelming," she revealed during an appearance on Jimmy Kimmel Live! earlier this month. Khloé added that it really comes down to "whoever won't annoy me."
