Both friends and fans took to the Married at First Sight star's comments to share their congratulations.
"Congratulations Liz. Best feeling in the world seeing bubba for the first time. I hope [your] hoo-ha gets better soon. You both will be such amazing parents!!!" wrote fellow Married at First Sight star Cyrell Paule.
"Ohhhh this warms my heart!!!! Congratulations beautiful (and GREAT choice of mama little one)," wrote Ten presenter Casey Beros.
"Yay she's finally here!! Congratulations honey, so happy for you all!!! Cannot wait to meet her. P.S. Her head of hair is exceptional!" continued MAFS season six star Melissa Lucarelli.
News of the couple's arrival comes just over six months since Elizabeth took to Instagram to share that she was expecting her first child, while also encouraging her followers to refrain from commenting on her changing body.
"[There's] always so much focus on a woman's body (I've had more than my fair share). I'm navigating my body right now [and there's] so many changes, especially internally."
"I also understand so many people are excited. So am I!!! It's an exciting time in our lives right now. I'll talk about my experience with [pregnancy] in the future. Mama bear is just nesting right now."
