Amber & Wiz Khalifa are about to make it official sooner than we thought.  Since she wants to wait until her belly isn't protruding out of her wedding dress, they're going the legal marriage route first.  Deets inside, plus pics of Tiffany Evans' new baby girl...

Rapper Wiz Khalifa and his fiance Amber Rose are in a hurry to make their union official.  So they're about to fill out the marital paperwork in the next few weeks, after he finishes up this tour, which will then make them legally married.  And a big ceremony (when Amber can fit into her wedding dress) will follow, after Amber pops out their brand new baby.  Wiz told Hot 97 in an interview recently:

"We're gonna get like license marriage.  A couple of weeks we're gonna have that done. I've said it, I don't think people really understood what I was saying. They're like, 'yeah okay, whatever.' Definitely, like in the next few weeks. Before or after I get off tour. You just sign the papers or whatever and it's like a legal thing. It's like 'Bam, you're married.' And then when you have the ceremony that's when you invite the family, she can fit into her dress."

As for whether their unborn baby boy was included in his upcoming album O.N.I.F.C. album dropping Dec. 4th:

"I actually did all the music pre-baby.  But the work and the grind and everything goes towards the baby though. I talk about Amber in the music though for sure."

So no baby cries a-la-Blue Ivy Carter here.  At least not yet.

In other baby fam news, singer Tiffany Evans showed off her new 2-month old baby girl Adalia Sarai Henderson:

Aww.  The new mom tweeted pics of her bundle of joy she and hubby Lorenzo Henderson welcomed into the world 2 months ago:

Too cute!  Tiffany's been posting about how happy she is saying:

My baby sleeps so peacefully....God has blessed me beyond what my eyes can see...thank you Lord.

Tiffany's preparing to perform in her church's Praisefest in December.  Still praisin' him....
