J Prince ﻿has a warning for Pusha T -- move on from the beef with Drake, or prepare to have your career squashed like a bug!

The Rap-A-Lot Records CEO told us Pusha's nothing more than an ant, and he issued a warning for the rapper. Some might hear that warning as more of a threat, but he says Pusha's got nothing to worry about, but only because he's not on Drake's level.

Despite the fact both Drake and Pusha have been dredging up ... J Prince assured us it's over and done.

You'll recall, Drake dredged up the old feud recently by ripping into Kanye West for betraying his confidence to Push. Then Pusha went on Joe Budden's podcast, claiming Drake's producer was the one who went all Judas to reveal Drake's secret son.

Despite the renewed jawing on both sides ... J Prince assures us the feud is dead and buried.
