Wiz Khalifa -- Blunts and Strippers Do a Daddy Good

Amber Rose wouldn't let Wiz Khalifa throw a birthday party with their kid -- according to Wiz -- so he settled for a wild party with strippers.

According to our strip club sources -- and these photos we obtained -- Wiz was droppin hundos Monday night alongside Snoop Dogg and Ty Dolla $ign at L.A.'s Ace Of Diamonds.

We're told the crew let tens of thousands slip through the g-string adorned cracks that night.

This probably won't help Wiz win his war with Amber -- or earn him a parent of the year award.

Then again ... strippers' kids gotta eat too.
