Bindi Irwin highlights her growing baby bump in new photo: 'There are no words'

Bindi Irwin has taken to Instagram to share a photo of her growing baby bump.

The Wildlife Warrior mum-to-be is seen with her hand caressing her abdomen and looking down with a contented smile.

"Dinner with the fam and baby bump," she told fans in the caption. "There are no words to describe how much I love our baby girl."

The 22-year-old and her husband Chandler Powell, 23, announced the news they are expecting a daughter at the end of last month.

They shared a social media post with a sonogram in hand telling followers: "Baby girl, you are our world. Our beautiful daughter is now about the same size as a hatchling Aldabra tortoise and is as healthy as can be. We can't wait for her arrival next year."

"Our little girl and my beautiful wife are my entire world. I'm so excited to meet our daughter when she's born next year and to see the incredible person she will grow up to be," Powell captioned his Instagram post.

The TV presenter and Wildlife Warrior gave followers their first look at her blossoming bump in a social media post two weeks ago.

"My beautiful mum took this photo yesterday," she captioned the photo. "Baby girl is doing great. Every time we get an ultrasound she's incredibly energetic and always moving around."

The couple vowed to share as much of the pregnancy with their loyal fan-base as possible.

Irwin recently revealled she's been feeling "tired all the time" and indulging in "pregnancy naps".

While it's not known exactly when the baby is due, it's understood the 22-year-old has just entered her second trimester.

Irwin and Powell announced they're expecting their first child in August, five months after they married in an intimate ceremony at Australia Zoo at the end of March.

The couple tied the knot just hours before strict coronavirus restrictions came into place in Queensland.
