Kawhi Leonard isn't getting a ring this season, but his girlfriend certainly did -- the NBA superstar's lady was spotted wearing a massive rock on THAT finger at the airport on Tuesday.
Which begs the question -- did the longtime couple get engaged?!?
TMZ Sports has obtained pictures of the Klaw and Kishele Shipley arriving at LAX ... and the mother of two had a shiny, new accessory on her left ring finger.
Leonard and Shipley have been dating forever -- they first met at San Diego State and have been inseparable ever since.
