Kylie Jenner is on fire!

The Keeping Up With The Kardashians (KUWTK) star is heating up Instagram with a photo showing off that post-baby body Jenner worked so hard to restore.

Kylie Jenner ravishing in red on Instagram

Kylie looks like she knows just how elegant she appears in that red strapless gown.

The Instagram photo highlights Jenner at her most sultry as well, with the mom of Stormi Webster with a hint of a smile on those slightly open red lips.

We’re loving the way that the satin fabric succeeds in keeping it demure yet…oops, she did it again!

Kylie has just a hint of sideboob on the side not covered by her gadget-holding hand.

Kylie has been exercising and dieting for months now, and the results are evident in that outfit.

But there’s another photo that Jenner recently posted on Instagram that has to do with a vision in red: Her daughter Stormi!

Us Weekly reported that Kylie gave her baby a truly over-the-top birthday party.

The first birthday party ever for Stormi Webster was held on February 9, with features including:

• a huge blow-up of the baby’s head that guests strolled through to get to the party
• a carnival ride
• party eats ranging from pretzels to tiny pizzas and drinks
• a butterfly rainbow forest

Do you agree with us that Kylie Jenner, at 21, has learned from the best (we’re looking at you, Kris Jenner), when it comes to how to give a kid’s birthday party?!
