Just who is Dwyane Wade's baby mama?

Leave it to TMZ to unearth the birth certificate for Dwyane Wade’s illegitimate kid. The LA based gossip site uncovered the document stating 30-year-old Aja Metoyer is the mother of the basketball player’s youngest son, Xavier Zechariah Wade, who was born Nov. 10. If you want to do the math, the baby was born six weeks before Wade asked Gabrielle Union to marry him. Maybe paid a large sum to do so, Metoyer (an ex of Damon Wayans Jr.) didn’t list the NBA star as the father but did give Xavier his famous dad’s last name.

No. 3 sure likes the Z names: his two children with high school sweetheart Siohvaughn Funches are Zaire and Zion.

The “A Father First” author admitted during a press conference last week that he had the child while he was on a “break” with Union. “I had a time, a part in our break, in our pain and our hurt, a blessing came out of it in my life, having a son that was born healthy.” But if you do the math, nine months before the baby was born, the power couple seemed hot and heavy in February, when the kid was conceived. “It’s me and my boyfriend,” Union Instagrammed with a pic of said bf and her bulldog Sasha, quoting the Toni Braxton ditty.

The next month (when the pregnancy tests kept coming back positive) the Mary Jane star began posting sad things like “Sometimes you have to get knocked down lower than you have ever been, to stand up taller than you ever were.”

Oh and as for Aja? Good luck Googling her. Her social media sites are all but nonexistent. All we know for sure is that she is 30 years of age and lives in L.A., likes celebrities and is very pretty. She has just 66 followers on a cryptic looking Twitter account @ajametoyer with only two posts. The last one quotes Beyonce: “If you’re comfortable in your own skin and you’re comfortable in my skin…”
