Nick Cannon is a father of 12!

On Thursday, Alyssa Scott shared that she and Cannon had welcomed their second child together on Dec. 14, a daughter named Halo Marie.

The couple previously welcomed their late son, Zen, back in June 2021.

A few months later, Cannon announced on his since-cancelled eponymous daytime talk show that 5-month-old Zen died of brain cancer and a subsequent tumour. 

The new baby news comes just over a month after Cannon welcomed his 11th child -- his third with Abby De La Rosa.

Cannon's growing family all started after he married Mariah Carey in 2008. Though the pair split in 2016, they share 11-year-old twins, Monroe and Moroccan. It was then that Cannon's "unorthodox" approach to dating and child rearing began, with Cannon going on to welcome 10 more children by five other women.

In the wake of Cannon's latest baby announcement, ET is giving you a guide to the 42-year-old TV personality's growing family.

Mariah Carey

Cannon and Carey married in 2008, and in April of 2011, they welcomed twins Monroe and Moroccan. Though the couple divorced in 2016, Cannon has continued to co-parent with Carey and remain a constant part of the twins' lives.

While it's been difficult for many to understand how Cannon juggles a busy career and his growing family, he told ET last month that he dedicates his "entire day" to his children.

"It's not as difficult as people think it would be, but I understand [their concern] because it is a very unorthodox scenario," Cannon explained.

"I dedicate probably my entire day to my children. Luckily, we are in a world where I'm blessed with the opportunity. I get to spend more time with my children every single day because of my world and my business model."
