Khloé Kardashian just shared the first snap of her and Tristan Thompson’s baby boy's face

Khloé Kardashian just took to Instagram to celebrate her ex, Tristan Thompson's birthday with a sweet photo of their new baby boy, whose face has just been revealed for the first time.

The 38-year-old, who welcomed the youngster with the NBA star in August last year via surrogacy, shared the post with her 297 million followers, which included other cute family snaps.

The first carousel shot shows Tristan with his arms around four-year-old, True, who he also shares with the reality star, and his six-year-old son Prince from his ex, Jordan Craig. All three are staring lovingly at the new addition to their family while snuggled up on the sofa together.

"Happy birthday @realtristan13 You are truly the best father, brother & uncle," the Good American founder captioned the tribute.

"Your love, attention, silly dances, hugs, carpool rides, bed time rituals, the way u show up for them. All of the above means more than you'll ever know to your family of littles."

Khloé then added her hopes for Tristan's next chapter, which include continuing to "crave change, healing, and transformation," plus being "strong," "kind," "patient," and "free."

The mum-of-two also honoured Tristan's late mother, Andrea Thompson, who sadly passed away in January.

"Continue to make your soul and your mommy proud. Happy birthday baby daddy," she concluded as she included a sweet mother-and-son snap of Tristan and Andrea in the post.

While Khloé and Tristan are now very much on co-parenting terms (after it was revealed he fathered a son with someone else before their baby boy - who is yet to be publically named - was conceived via surrogacy), the pair have been spotted at numerous family events.

From the 38-year-old attending Andrea's funeral along with her mum and sister, Kris Jenner and Kim Kardashian, the ex-couple recently both attended Khloé's best friends' Malika Haqq and twin sister Khadijah Haqq McCray's 40th birthday party.
