Brandon and Leah Jenner Are Going to Be Parents!

The Kardashian-Jenners have a new cause for celebration: Brandon and Leah Jenner are starting a family. On Sunday, Leah announced that she's pregnant in an adorable Instagram. "Well, it's time we share the good news," she wrote in the caption. "We're having a baby." The picture-perfect moment shows Brandon embracing and kissing his wife as she looks at the camera and holds her baby bump.

Even though the baby will be their first, the couple is very familiar with the joys of parenthood. Throughout the past few years, they've seen Brandon's stepsisters create families of their own. While Kim Kardashian and Kanye West have been sharing the spotlight with little North West, Kourtney Kardashian and Scott Disick are parents to Mason, Penelope, and Reign Disick. As if Brandon and Leah's news couldn't be more exciting, it comes just before the season 10 premiere of Keeping Up With the Kardashians on Sunday. The music duo has made several appearances in scenes with Brandon's dad, Bruce Jenner, and sisters Kendall and Kylie Jenner in recent years.
