Drake's 37th birthday party was one for the chemistry books, featuring "Breaking Bad" stars Bryan Cranston and Aaron Paul as bartenders to mix up some special cocktails at Casadonna in Miami.

The two stars showed up floral shirts and all to Drake's Miami bash Monday ... which likely served as an easy promotion for Bryan and Aaron's Dos Hombres mezcal brand.

Of course, these guys have racked up Emmys, Golden Globes and AFI awards playing meth lab whizzes Walter White and Jesse Pinkman on the show … and their bartending skills look to also be on point.

As for the location, Drake held his bash at David Grutman and Noah Tepperberg's Casadonna, an Italian-inspired restaurant along the coastline. Drake was decked out in all-black, and his friends and fam teased him for having an abundance of mango juice -- instead of his usual go-to passionfruit.

Nonetheless, the OVO crew all rallied around to toast him -- and tease him for making them all "Rich Baby Daddies" … as his new hit with Sexxy Red and SZA suggests.
