The proud 25-year-old papa (real name Cameron Jibril Thomaz) made the announcement via Twitter, writing, "Happy Birthday Sebastian 'The Bash' Taylor Thomaz!!! Everyone welcome this perfect young man into the world."
This news comes after yesterday's false alarm, when Amber went in for a doctor's appointment that became blown out of proportion.
"My due date isn't until Feb 24 & this is my first baby so he may come early, he may come late but either way he'll be here soon," Amber, 29, clarified on Wednesday.
The couple, who announced their engagement last year, are planning to hold off on a formal wedding ceremony until after Amber has a chance to drop the baby weight.
"If we have a daughter one day, [Amber] might wanna give the dress to our daughter, but if she's pregnant then she can't do that," Wiz explained to Hot 97's Angie Martinez in November.
