WTF?! Tyga MUST have been joking when he claimed in a now-deleted Snapchat Friday, that Kylie's unborn child is "his kid," right?!

Kylie's ex-boyfriend must be insanely jealous and super-pissed that he didn't lock it in with Kylie but that Travis Scott did the deed. But fans are speculating that it's not necessarily a given that Scott IS the father. He and Kylie haven't been seen together for a while -- we haven't photographed them together since August 10th when they celebrated Kylie's 20th birthday together. So is it possible Kylie had a rebound hookup with T-Raww and got pregnant and is just now taking a pregnancy test a month later and realizing she's with child?! Oh, the possibilities!

Meanwhile, Kylie's mom is reportedly HAPPY about the news -- a source tells Us Weekly: "Kylie loves how close knit her family is and is thrilled to bring that to her immediate family. Kylie feels more prepared than ever to be a mom." Ha! True, an uneducated girl under drinking age and single is totally ready to be a mom. Just because you're rich doesn't make you maternal material!

The mag also claims Kylie and Scott broke the happy news to friends earlier this month that they're expecting a GIRL and that Kylie's four months along already. Fans point to a Tweet from Scott on June 12, in which he wrote: "Legit happiest day of my life." Is that they day Ky took the pregnancy test and found out?

Kris Jenner said to the Hollywood Reporter when asked to confirm Kylie's pregnancy: "It wouldn’t be the family if something didn’t happen every single day." Uh, what?!

And if all of this isn't confusing enough, the supposed baby daddy Travis Scott wasn't even in LA yesterday as the big news broke -- he was in Miami for a performance at LIV nightclub at the Fountainebleau and Scott Disick was chilling with him! Was Scott congratulating Travis on his entry into the Kardashian Klan? Eh, who are we kidding -- Scott was just partying and chilling with Sofia Richie; he doesn't care about the Kardashians!
