How's Justin Jefferson rewarding himself for ballin' the hell out during his rookie season?!
BLING, BABY!!!
TMZ Sports has learned the Minnesota Vikings star receiver just copped a new diamond chain featuring a jet pendant ... and it's AWESOME!!!
We're told the wideout hit up Leo Frost in Houston a few weeks ago to get the ice made ... and the famed jeweler sure as hell delivered.
The jet -- an obvious nod to Justin's "Jet" nickname -- is iced out ... while the chain features stars on the links.
