Omarion has a whole new reason to sing "Girlfriend" — considering his is pregnant! The 29-year-old R&B star posted a video of lady love Apryl Jones's sonogram, confirming that the couple has a little one on the way!

"Say hi :) #comingsoon #thelegacybegins," Omarion writes in the Instagram caption. "@aprylsjones is my heart. What a great gift! #ecstatic"

Apryl posted the same sonogram with the message, "Hi, Daddy @1omarion Another king is born. #greatestdad #newmom"

Omarion — born Omari Ishmael Grandberry — shared his elation with Vibe, raving, "I'm just really excited about the process. I'm the type of person that loves putting my energy in things and seeing the outcome. To have someone that's like me, that's gonna be my genetic gene code? The way I think, the way I act, the way I walk, just everything. That's the coolest thing you can ever do in your life, so I'm just excited."

The former B2K member also shared that he and Apryl don't know the baby's sex yet — but they do have a preference: "We hope we're having a boy. We're willing it to be a boy."

And the Sex Playlist singer is thrilled to talk about his upcoming bundle of joy at any opportunity: "This is a moment that I'll look back on, my child will look back on and say, 'Damn, that was dope. My pops said this. He didn't try to hide me or make me into this weird thing.' No, son [or] daughter — you are special, and that's just what it is."
