Pregnant Khloe Kardashian hides 'baby bump' under baggy black jumper in unusually comfy look for KUWTK filming

 The reality star was spotted in this comfy look on set on Tuesday

Khloe Kardashian did her best to keep her baby bump hidden while filming scenes for Keeping Up With The Kardashians in a Los Angeles studio on Tuesday.

The reality star, who is thought to be expecting her first child with boyfriend Tristan Thompson, is yet to publicly comment on the baby news.

And in what appears to be a bid to still keep it well underwraps, the star was spotted on the KUWTK set unusually dressed in a baggy black sweater.

While she's normally dressed in form-fitting bodysuits and tight high-waisted jeans, Khloe opted for comfort, teaming the jumper with sweatpants and Chanel sliders.

Just days before, she appeared to show no hint of a bump when she shared a snap from sister Kim's baby shower.

Keeping fans guessing, Khloe stunned in a short lilac lace frock as she posed outside Kim's cherry blossom-filled home.

"Cherry Blossoms and Tea for baby number three," she captioned it.

It was previously reported that she's expecting a baby boy with her NBA star boyfriend.

It will be Khloe's first child and Tristan's second son - he welcomed son Prince with ex-girlfriend Jordan Craig back in December 2016.

Meanwhile, a source recently opened up about Khloe's diet now she's eating for one more.

"She’s hungrier than ever and opts for smaller meals throughout the day to stay on track with her diet while eating for two," they shared.

They also said that an engagement is soon to be on the cards, adding: "They are just waiting for the right time to move forward and get married.

"Khloe doesn’t want to rush into anything.”
