Tristan Thompson is feeling fatherly, apparently ... he posted pix of son Prince, 2, and daughter True, 13 months, to his Instagram Story -- he was NOT, however, feeling it with his babies mamas on Mother's Day when he snubbed Khloe Kardashian and Prince's mom Jordan Craig. He did, however, honor his own mom by posting this message to Instagram: "Happy Mother’s Day Mommy. I love you soo much I’m so blessed to have a mother that loves me the way you do and willing to sacrifice everything for her kids."

On his Instagram story, the photo of son Prince is of the tyke in a little boat, which he captioned, "Mi bwoy [sic] sweet." And on the image of True reading a pic is written, "My little scholar." With that grammatically-incorrect caption on the pic of his son, we think Tristan might wanna brush up on his scholastic endeavors, too!


Tristan's not the only of Khloe's exes in the news -- Lamar Odom, the NBA'er Khloe split from five years ago, writes in his new memoir about regret: "I wish I could have been more of a man,” Odom told People. "It still bothers me to this day. But regret is something we have to learn to live with." He admits to cheating on Khloe and hiding his cocaine addiction from her in the book Darkness to Light. Sounds like a summer beach-time must-read!
