Kylie Jenner Finally Revealed in Calvin Klein Ad

Pregnant Kylie Jenner finally showed her face for the first time in nearly 5 months ... 'cause mama-to-be's still gotta bring home the bacon.

Kylie posed in bed with her sisters -- Kim, Khloe, Kendall, and Kourtney -- while rocking their Calvin Klein undies, but she was careful to NOT reveal what everyone's waiting to see.

Obviously, the product shot was a scheduled advertisement, but while all the other sisters showed their lower halves ... Kylie hid her baby bump under a blanket, showing only her bra. Even pregnant Khloe only covered her belly with her hand.

Sorry, Calvin ... mom boobs are all you get from KJ. For now.
