Wollover, 26, gave birth to Maven at 12:03 a.m. in New York City, the rep tells Us. The newborn bundle of joy weighed in at 7 pounds, 3 ounces, and measured 19.59 inches long.
Maven is Morgan's fourth child but his first with his fiancee; he also has three grown sons from his marriage to ex-wife Sabrina, whom he divorced in 2009 after 23 years of marriage. In an interview with Rolling Stone earlier this year, he said he hoped to add a daughter to his brood.
"You know what happiness?" he asked the mag. "Happiness is a simple thing, man. It's having something to look forward to."
Morgan, 44, has a whole lot to look forward to now that he has a new baby. Shortly after Maven's birth, he tweeted excitedly, "Its A GIRL!!!!!"
