Could it be??? Is Kylie Jenner pregnant with the second baby she's been wanting?

Little Stormi and her parents Travis Scott and Kylie enjoyed a family lunch on Mother's Day and we wonder if they weren't celebrating news of a second child, too! Ky wore a skin-tight dress and either she enjoyed a big brunch OR she's showing off the very beginnings of a baby bump and we're hoping it's the latter!

We know the KarJenners like to time their pregnancies to coincide and obviously half-sis Kim Kardashian and her hubby Kanye West just welcomed their fourth child, so could Kylie be hoping for a sibling for Stormi who'd be just a few months younger than his/her cousin?
