Kenny "The Jet" Smith just added another highlight to his reel -- the "Inside the NBA" host popped the question to his girlfriend -- and she said YES!
The NBA champ's new fiancée, Tia Jurcic, revealed the engagement on her Instagram ... showing off a huge diamond ring on that finger with a beautiful beach view serving as the backdrop.
The soon-to-be married couple have mostly kept their romance under wraps, though Jurcic shared their first photo together last February at a Super Bowl event.
