Earlier this month, Azalea shared another too-cute photo of Onyx on Instagram, reflecting on how big her little boy has gotten.

In the photo, Onyx is crouched on the floor and watching something on his iPad.

"I took this picture because he looks like such a big kid to me now!" Azalea wrote. "Not long until my baby turns 1! 💛"

Back in January, the rapper shared some never-before-seen photos of Onyx as a newborn, reminiscing on her time as a mom.

"Photo dump//mommy & onyx 2020. I really Can't believe how fast time flys [sic] 🥺 he looks like a toddler now days!" she wrote alongside the photos on Instagram. "Just yesterday you were a tiny ball in my arms. 😩💖 I love you always, all the ways."

Azalea first announced the birth of her child on June 10, writing on her Instagram Story at the time, "I have a son. I kept waiting for the right time to say something, but it feels like the more time passes, the more I realize I'm always going to feel anxious to share news that giant with the world."

The new mom then shared that she wished to "keep his life private but wanted to make it clear he is not a secret," adding, "I love him beyond words."

Azalea and her ex Carti met in 2018 while she was touring overseas and began dating shortly after. Three months after they confirmed their romance, the musicians decided to move in together, with Carti confirming the big step in their relationship in a summer 2019 cover interview with Fader.

However, in October, Azalea confirmed that they had split, but reassured her followers that Carti would be involved in Onyx's life.
