Is Kylie Jenner pregnant? This tweet certainly suggests so…

Fans on Twitter have been going crazy all morning after a mystery tweet seemed to suggest that Kylie Jenner is pregnant.

The tweet appeared on Kylie's sister Kendall's page and showed a pregnancy test with the caption: "I don't care what anybody says. congrats @Tyga."
