Tristan Thompson is spending some quality time with his oldest child.

The NBA star, 34, took to Instagram on Monday, Aug. 25, to post new photos with his son Prince, whom he shares with ex Jordan Craig.

In the first snap, Thompson and Prince can be seen posing in matching white shirts while flashing peace signs for the camera.

A second shot showed the youngster enjoying three-layer red velvet cake.

“Twin,” Thompson simply captioned the photos.

Khloé Kardashian, who shares daughter True, 7, and son Tatum, 3, with Tristan, dropped a comment under the post, writing, “Prince is too cute!”

Fans also weighed in on who the 8-year-old resembles most.

“True/Prince are twins which makes you all triplets,” one joked.

“He is so handsome, perfect combination of you and his mom,” another chimed in.

A third disagreed, insisting, “He’s a mixture of you and his mom, True is your twin lol.”

Tristan Thompson, who also has a 4-year-old son, Theo, with Maralee Nichols, has been sharing more glimpses of his blended family. Back in July, he posted photos from Tatum’s third birthday party, where all four kids came together for the celebration.

The basketball pro captioned the post, “Big hugs and kisses for my little Tatum’s Bday! I Love you forever young king. This just the beginning more pics to come.”

Earlier this month, Thompson also shared a Reel of Prince heading back to school. The clip showed the third grader sitting up front in the car with his dad before walking into class.

“Big third grader. What are you most excited about [for] third grade?” Tristan asked in the video.

Prince happily revealed his list of wishes for the school year, which included taking home a classroom Chromebook because students can bring them home and back to school, earning third-grade prizes, and collecting merchandise from YouTube star Mr. Beast.
