Kenny "The Jet" Smith might be in the middle of covering the NBA playoffs, but he's still finding time for R&R -- the "Inside the NBA" analyst hit Miami Beach with a stunning woman on Thursday ... and TMZ Sports has the pics!!
Smith -- who's been a regular on TNT for decades -- ditched his shirt and threw on some red trunks to catch some rays in Florida ... and had model Aline Bernardes right by his side for the occasion.
It's unclear if the two are dating -- they didn't show any PDA throughout their beach visit, but Bernades DID put him on Instagram for her 207,000 followers to see .
