We got video showing TT outside the class Monday, about an hour before his lengthy post where he revealed he was the father of a baby boy. Tristan sat in a waiting SUV while someone from inside the class brought out what we're told was close to 100 roses.
A source close to Thompson tells us the flowers were for True, who he hadn't seen in a few days -- The Sacramento Kings are in town to play the L.A. Lakers Tuesday.
As we reported, Tristan says a paternity testproved he's the father of Maralee Nichols' baby boy, born last month in Houston. The two had been locked in a nasty back and forth in court, but now the NBA star says, "Now that paternity has been established, I look forward to amicably raising our son."
He then turned things to Khloe -- who he was publicly dating when he got Nichols pregnant -- saying, "You don't deserve the heartache and humiliation I have caused you. You don't deserve the way I have treated you over the years."
Tristan concluded, "My actions have certainly not lined up with the way I view you."
Tristan and Khloe split in May ... and we've spoken to sources who say there's absolutely no chance at reconciliation with their relationship -- the two will only continue to co-parent.
