Bindi Irwin shares heartwarming video of unborn baby during ultrasound appointment: 'The light of our lives'

An emotional Bindi Irwin has given fans a first glimpse of her unborn baby.

The Wildlife Warrior and her husband, Chandler Powell, posted a video of their ultrasound appointment to Instagram, with both choking up seeing their first child on the screen.

"Our beautiful daughter is the light of our lives," 22-year-old Irwin said of the video. "Beyond thankful that she chose us to be her parents. I can't wait for her to be here next year."

Powell, 24, was equally moved during their appointment.

"The most beautiful sight in this world," he commented on Instagram. "I love you."

In the short clip, the dad-to-be — who was behind the camera — was in awe as he proudly zoomed into the image of their child. 

"Wow, you can see her heartbeat there. Oh my goodness, she is beautiful and very active," he said he said on camera after his wife gushed, "This is so exciting. Look at our daughter. She's so beautiful."

The parents-to-be have been happily sharing updates on their pregnancy with fans since announcing the happy news back in August. The following month, they shared a first sonogram image of their daughter, then weeks later they revealed their baby's gender.

"Baby girl, you are our world," Irwin posted at the time which she accompanied with a photo of the couple embracing a tortoise while holding a sonogram image of their little girl.

"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."

Irwin is just a little over halfway through her pregnancy. Two weeks ago, she revealed she was 20 weeks pregnant and excitedly counting down the days until the birth. 

"Halfway there! 20 weeks pregnant and our baby girl is about the same size as a recently hatched emu chick," she said. "The love I have for my sweetheart husband and our beautiful daughter is boundless."
