Looks like someone is on Daddy Duty. Tristan Thompson took to social media to share some photos with his son, Prince, on April 27, and it seems as though Khloé Kardashian‘s baby daddy is getting in some boy time with his little guy — something we rarely get to see.

“We had the best time at Cali’s Birthday party,” the 28-year-old captioned a series of three photos he posted to Instagram of himself and his son at a friend’s birthday party.

The first photo shows Tristan grinning widely as his son sits on a horse, while the other two photos show the duo amongst party balloons and teaming up to blow some bubbles together. Prince’s mama, Jordan Craig, didn’t seem to be around, so we didn’t get any cute family pics, sadly.

We had the best time at Cali’s Birthday party!!

A post shared by Tristan Thompson (@realtristan13) on

It’s been a few months since we got a glimpse of little Prince, who turned 2 on December 12. His dad shouted him out on Instagram, naturally, and we were lucky enough to get a few rare snaps of the sweet boy.

“Happy birthday to my son Prince, so blessed the man upstairs chose me to be your pops,” Tristan captioned the series of two photos, including one of the toddler holding a basketball — possibly foreshadowing a future b-ball career like his dad. “You’re my motivation every day. Daddy loves you so much!!! 👑HeartHeartHeartHeart #MyTwin.”

To be fair, we don’t see the Cleveland Cavs player posting many photos of his daughter, True, either. But, on the flip side, he isn’t exactly in the picture all that much. Between his basketball schedule and living most of the time in Ohio, the dad-of-two definitely finds it harder than most to get out to the west coast for his kids.

That aside, his relationship with Khloe, 34, isn’t exactly in the best place right now, which also might be why we’ve seen less of him in dad mode. He did make an appearance at his daughter’s first birthday bash, but other than that, he’s been a bit of a ghost.

Good to see you doing your dad thing, Tristan.
