The Chicago natives have been going strong for well over a year and Common had no problem bigging up his partner ... dubbing her one of the "greatest voices of this generation" oughta score him some points this holiday season.
Common's praise echoed much of what Jennifer told us when we spoke to her in August ... they're not embellishing their union for the public eye, but they're not dodging the PDA moments either.
It's not like Common can really overhype his woman -- Jennifer is the youngest woman to earn EGOT status, and he's just a Tony away from joining that elite status.
They're arguably the most critically acclaimed couple of all time!!!
