Kylie Jenner poured more fuel on the pregnancy fire Wednesday when she canceled an appearance on James Corden's talk show.

The 19-year-old's sister, Kendall, explained that the beauty mogul had to bail because she wasn't feeling well, even though she was photographed out just a few hours later.

It was also reported that the teen's boyfriend Tyga, who's already dad to a four-year-old son named King, would love to have a child with the reality star.

"Kylie and King have a special connection and it’s really making her think of having a kid with Tyga," a source previously revealed. "He told her one of his greatest joys is being King’s father and that he’s down to father a child with Kylie."
