Kardashian fans the world over rejoiced when Bruce Jenner’s middle son Brandon announced that he and wife Leah were expecting their first child.

The couple married in 2012 after dating since they were teenagers and work together as music duo: Brandon and Leah.

The California-born blonde (who is daughter of Eagles guitarist Don Felder) shared a pregnancy update via her Instagram page

Leah, 32, looked calm and relaxed as she rested in her Malibu living room, balancing a Starbucks cup on her growing belly.

She captioned the pic with: “I could get used to this pregnancy thing #nextmonthTVdinner.”

Leah was a massive support to sister-in-law Kim Kardashian whilst she was expecting daughter North West, now 21 months.

The musician took Kim, 34, to pre-natal yoga sessions as well as encouraging her to embrace her pregnancy shape.
