Kylie Jenner took to Instagram on Saturday to share a brief snippet of her niece True Thompson’s birthday celebration.

The 25-year-old billionaire mogul — who was active on TikTok earlier in the day — used the platform’s Stories feature to post a video of 5-year-old True, her cousin Dream Kardashian, 6, and a third little girl.

The youngsters were dressed in matching mock neck pastel dresses with rhinestone green figures adorned on them.

The birthday girl was dressed in pink while her cousin, the daughter of Rob Kardashian, wore a blue variety.

A small girl in a lavender dress and white combat mini boots with black laces rounded out the trio.

Kourtney Kardashian, Kylie’s 43-year-old big sister, also uploaded an outtake from the festive day.

The POOSH founder took to Instagram as well, posting a snapshot of True’s blue, green, and yellow ocean-themed cake.

In Kylie’s video she trailed behind her nieces and asked, ‘Whose birthday is it?’

They all turned around in unison as two shouted ‘True’s!’ and the birthday girl shyly pointed toward herself.

True, whose father is mom Khloe Kardashian’s NBA star ex-boyfriend Tristan Thompson, wore her hair in a voluminous curly ponytail with two strands left out at the front.

She was decked out in glinting diamond jewelry, including stud earrings, a nameplate necklace, and a flashy bracelet.

Kylie also shared a look at her mom Kris Jenner’s fashionable pantsuit, which was in theme with its muted pastel green hue.

She carried a small, matching designer handbag with a pristine nude pink manicured hand.
