Khloe Kardashian is officially the anti-Kylie Jenner.

Whereas the reality star's half-sister is doing everything she can to avoid the spotlight these days and remain mum about her pregnancy, Khloe is now going in the opposite direction.

She's embracing every aspect of this whole expecting thing.

On Tuesday afternoon, Kardashian shared a couple of very sweet images on her Instagram account, both in celebration of a big milestone.

The mother-to-be is now six months along, as she confirmed in a very simple caption that accompanied the picture above.

This means she's headed into her final trimester and will likely give birth in late March or early April. How exciting!!!!!

Khloe, of course, did keep quiet about this major news for awhile.

But she finally let loose about the bun growing in her oven back on December 20, sharing an adorable photo of her baby bump along with a lengthy caption.

"My greatest dream realized! We are having a baby!" gushed Khloe at the time, adding in her extreme excitement:

"I had been waiting and wondering but God had a plan all along. He knew what He was doing.

"I simply had to trust in Him and be patient. I still at times can't believe that our love created life!"

It certainly is true that Khloe has been open over the years about her desire to procreate.

It didn't work out with Lamar Odom due to his drug habit, and then she was never serious enough with rebound lovers James Harden or French Montana.

But it's been clear for awhile now that the romance with Tristan Thompson is legitimate and serious; both seem pretty darn psyched to become parents.

"For six months, you a fine six months, baby. I'll tell you that," Tristan told Khloe in a Snapchat video this week, while the latter wrote as a romantic caption to the following photo:

Mom and Dad.

That really does say it all, doesn't it?

So, why is Khloe being so open about her pregnancy, while Kylie is basically in hiding?

Well...

• She's very clearly with her baby daddy, while the relationship status between Kylie and Travis Scott is unknown.
• She's 33, while Kylie is 20.
• Khloe cares about her body, but she hasn't made a living off sharing sultry images in the way her sibling has, which would explain why Kylie is ashamed over her shape these days.

These are all just guesses, of course.

We can't say for certain what's going on with either of these women. We can only post what we see online and hear about from various sources.

Whatever the case may be, we simply wish a healthy pregnancy fo both Khloe and Kylie, along with very happy and healthy babies.
