Wiz Khalifa, Amber Rose -- Divorce Settlement ... You Get a Mil, I Keep My Whips

Amber Rose and Wiz Khalifa celebrated their divorce Monday night at a strip club, and now we know why ... each did more than okay in the settlement.

Amber and Wiz filed their settlement agreement with the court, and the headline ... she gets a cool million under the prenup. Wiz has already paid $356k, so he still owes her $644k.

But Amber gets more ... $14,800 a month in child support for their 3-year-old son, Sebastian, with whom they share legal and physical custody.

As for Wiz ... he gets the Pennsylvania home and 10 cars, including a '69 Chevelle, a '68 Camaro, a '62 and a '64 Impala and a Porsche, of course, of course.

Biggest thing ... they're both good with the way the divorce ended, which is ultimately good for the kid.
