In a video the Good American founder shared to her Instagram Story - one of many videos and pics from the birthday party - Thompson can be seen off to the side of the frame, posing with Khloe and True for photos in front of the balloon wall.
The NBA player has barely been on social media, ever since his "cheating" scandal with Jordyn Woods came to light.
"True-ly Perfect", Thompson began his post.
Year after year the Kardashian family continues to grow starting with Kourtney Kardashian's kids, then Kim Kardashian West's brood and now both Khloe and little sister Kylie Jenner have joined the club with their baby girls. Today and until the end of time, I love you! Can't wait for us to sit home all day and watch lion king and paw patrol lol.
True, whom Khloe has with Tristan Thompson, is set to celebrate her first birthday yesterday, and the 34-year-old reality star has said she's starting to feel nervous about the big day.
However, the epic bash - which kicked off Sunday afternoon, two days after True's actual birthday - wasn't all awkward. "You are my ultimate True love!"
"I am honoured and so thankful to be your mommy!" I'll be happy, of course, I simply can't understand where the time goes.
"Khloe hopes by the time [True's] birthday rolls around, her and her family will be able to be cordial towards Tristan", a source told E!
It is unclear if Tristan Thompson, True's father, will be invited. This is why she kept defending Tristan amidst his unveiling mistakes and constantly tried to find reasons to reconcile, hoping it would magically get better.
