Bruce Jenner's son Brandon expecting first child

Los Angeles: Former Olympian Bruce Jenner's son Brandon Jenner and his wife Leah are expecting their first child together.

Leah announced the happy news on Instagram debuting a photo of her baby bump, reported Ace Showbiz.

In the photo, Leah could be seen caressing her baby bump while being kissed by Brandon on the cheek.

The 32-year-old TV personality wore a green cleavage-baring, flower print dress and her hair was styled in loose waves.

She captioned it, "Well, it's time we share the good news. We're having a baby."

Brandon tied the knot with Leah on May 31, 2012 in Hawaii outside the St Regis Princeville Resort.

At that time, they were feted by family including Bruce, Kris Jenner, Kendall Jenner and Kylie Jenner. Brandon's step sisters Kim Kardashian, Khloe Kardashian and Kourtney Kardashian were unable to come due to work commitments.

The couple, who performs in the indie pop group Brandon & Leah, has appeared numerous times on "Keeping Up with the Kardashians". Their single "Showstopper" was used as the theme song for the third season of "Kourtney and Kim Take Miami".
