Azalea – whose real name is Amethyst Amelia Kelly — and Carti first met in 2018 while he was touring overseas and started dating shortly after. Azalea confirmed the pair had split in October 2020, following the birth of Onyx in the summer of that year.

In 2021, Azalea opened up to PEOPLE about the juggling act of being a mother, entertainer and now, running her own cosmetic line, Totally Plastic.

"Honestly, it's definitely really hard, but that makes it super fulfilling. I feel way more accomplished to know that I am able to do all these things at the same time," The End of an Era rapper shared. "But sometimes it can be very stressful. I like to spend the whole day with my son, and he doesn't go to bed until 7 o'clock. That's when the clock starts for me, whether it's in the studio or working on other creative projects. I don't go to bed until 4:30 in the morning, and my son wakes up at 7:30."

"It's a never-ending cycle of balancing what I want. I have big respect for other working moms," she added. "Whether you're an entertainer or whatever you do, it is a tough balance, but it's really fulfilling. I love knowing that all the projects I'm doing are things that my son's going to get to see one day and be like, 'My mom was really cool. Look what she did.'"
