Did Tyga Knock Up Kylie Jenner?

Tyga's not-so undercover girlfriend Kylie Jenner has been looking more voluptuous lately. Some have attributed the transformation to plastic surgery, but a source who spoke to In Touch magazine had another explanation; The little Kardashian is pregnant with Tyga's child.

"She just found out," the source said. "She loves Tyga and sees a future with him. She's happy."

Kylie's mother, Kris Jenner, not so much.

"She was screaming, telling Kylie she was going to kill her and that she never should have let this happened," the insider added. "Kris tried to ban Kylie from dating Tyga. Kylie told her to mind her own business."

There were also reports last week that big half sis Kim Kardashian had tried to prevent Kylie from seeing Tyga.

Tyga and Kylie have held off on making their relationship "official" because Kylie is 17 and California's statutory rape laws cut off at 18. How the authorities would deal with a pregnant Kylie is anybody's guess.
