Nick Cannon Welcomes Baby No. 12, Daughter Named Halo with Alyssa Scott

Nick Cannon is likely already reallllly good at changing diapers, but he's about to get even more reps in ... as he just welcomed baby number 12 to the world.

Alyssa Scott, who Cannon previously had a child with, broke the news Thursday -- revealing their daughter, Halo, was born on December 14. Scott says, "I will remember the sound of Nicks voice saying "it's a girl" and the look of everything we've been through flash across his face."

She continues, "I will remember the sound of her crying out with her first breath and feeling her heartbeat against mine. My sweet girl, I got my surprise!! We love you Halo Marie Cannon!"

Previously, Nick and Alyssa had a baby boy together named Zen, who died at only 5 months after brain cancer.

Scott remembered Zen in the announcement of Halo, writing, "Zen is in every breath I take. I know his spirit was with us in the room that morning. I know he is watching down on us. He shows me signs everyday. I will hold onto this memory forever."
