Kendall Jenner may be the only Kardashian/Jenner sister who doesn't have a child on the way.

As Kim Kardashian and husband Kanye West prepare for the birth of their third child, via surrogate, and Kylie Jenner and Khloe Kardashian face rumors claiming they are expecting their first children, Jenner is enjoying a new romance with Los Angeles Clippers player Blake Griffin.

“With all the baby news flying around her family, Kendall found herself thinking about what it would be like if she were pregnant too,” a source told Hollywood Life on October 11. “She is nowhere near ready to start a family with her new boyfriend Blake but the pair are heating up and have joked about what an amazing athlete their son would be, if they had a boy. Kendall was joking with Blake about their incredible genetics that would produce a super athletic baby capable of going to the Olympics, playing in the NFL or definitely in the NBA."

Jenner and Griffin were first seen together in August of this year in Los Angeles. Since then, the couple has been photographed together in New York City and Long Beach, California.

"She is tall and Blake has height too so their kid would be tall for sure. Oh, and if they had a girl, well she thinks she would be gorgeous and tall enough to do runway too, just like her momma," the source added.

Before Griffin, Jenner faced rumors of numerous romance with the likes of Jordan Clarkson of the Los Angeles Lakers and rapper ASAP Rocky. That said, she never went public with either of the men.

To see more of Kendall Jenner and her family, tune into new episodes of Keeping Up With the Kardashians season 14 on Sunday nights at 9 p.m. on the E! Network.
