Are Kylie Jenner, 20, and Khloe Kardashian, 33, finally coming clean about their pregnancy news?

During a video ad for Kylie Cosmetics, the two sisters sat down to try on and talk about their joint "In Love With The Koko" lip kit collection.

As they puckered up to show their different tones, the blonde dynamic duo joked about "twinning" in their nearly identical looks and outfits, later gushing about their creations and calling them their babies!

"It's our baby together! We have eight!" screamed an excited Khloe.

"I know, we have so many babies," said a sarcastic Kylie. "Who knew?"

The two pregnant sisters glanced at each other with knowing looks before bursting out into laughter and sharing a hug.

As Breaking Celebrity News readers know, Khloe and Kylie are both pregnant with their first child. Various sources have confirmed the news – as has Caitlyn Jenner's rep – but the KUWTK ladies have yet to speak out about their growing baby bumps!
