Tristan Thompson is finally clearing the air about the circumstances under which he met Khloe Kardashian ... and he's also defending his other baby mama.
Tristan on Wednesday debunked a report he had reunited with his first baby mama, Jordan Craig. There were reports Tristan, Jordan and their 2-year-old son, Prince, recently went on family vacay in Jamaica ... making it seem as if they were rekindling an old flame.
Tristan says there's ZERO truth to that ... and adds he's spent the last few months preparing for the NBA season, and that's it -- zero summer vacations.
