The adorable cousins spent time together over the weekend, which True's famous mom, Khloe Kardashian, documented on her Instagram Story.
Khloe first posted pics of True sitting near Rob Kardashian's 2-year-old daughter as they played with sidewalk chalk. In the pics, Dream looked like a princess in a blue tutu dress and silver headband as 1-year-old True rocked a red-and-white tie-dye look.
Later, True and Dream had a magical bash, complete with grownup fairies there to entertain the girls. For the occasion, Dream rocked the same blue dress -- this time with a matching hair tie and coordinating fairy wings -- while True wore a similar pink look, to which she added a unicorn headband and flower crown.
The cute cousins spent time together back in August, which Rob -- who shares dream with his ex-fiancee, Blac Chyna -- documented on social media.
At the time, the duo sported swimsuits as they lounged at the pool, with Dream opting for a floral one-piece, dramatic straw hat, and pink sunglasses, while True wore a cherry-printed suit with a white hat.
"My little lady acts like she's 50 years old," Rob quipped of his daughter.
Khloe -- who shares True with her ex, Tristan Thompson -- also posted a shot from the sweet day, which featured the two girls munching on snacks from their high chairs. "Happy Sunday," she wrote alongside the pic.
