Holy cuteness, Batman!

Rob Kardashian posted what is possibly the most adorable picture of his niece, Penelope Disick, oh, ever.

In the sassy snap, Penelope, the middle child of Kourtney Kardashian and now estranged boyfriend Scott Disick, is showing off her choice style in a Parisian-inspired ensemble: A black-and-white cropped tank and black tulle skirt paired with a long chain necklace, bright red purse and '70s-esque round sunglasses.

Rob was quick to point out the toddler's leaning pose and mischievous smile.

"Hey P‼" Rob wrote. "Lol she think she so cool… I LOVE HER!!"

How's that for a doting uncle? This is the first current photo Rob has posted on his Instagram account, which, unlike his social media happy sisters, he only started two months ago.

Penelope turned three last week on July 8, and Kourtney celebrated by taking her daughter on a birthday trip to Disneyland.

You forever changed my life and my heart and teach me so much everyday. Happy birthday my tinkerbell angel. 💚💫

How cute is it that they both dressed up like Tinkerbell?!

WATCH: Kourtney Splits From Scott

The mother-daughter duo wasn't alone -- they were joined by Kourtney's sister Kim Kardashian and her equally Disney-obsessed daughter North West, an infamous Minnie Mouse fan.

MVP goes to @kimkardashian for hanging with my crazy Disney obsessed self for 12 hours of major madness. #Disneyland

Considering the rough time Kourtney is currently going through as she deals with the aftermath of her split from Scott, the delightful Disney day trip and fun Instagrams from family members are sweet reminders that the Kardashians have each other's backs no matter what. 

Just how stressful a month has it been for Kourtney? See her latest pics in the video below.
