Kourtney Kardashian and Scott Disick may have had a rocky relationship over the years, but they sure did produce some cute kids.
Just look at this adorable pic of their daughter Penelope, who turns four years old today.
I mean, what a sweetie.
Kourtney shared the pic to Instagram today with a sweet message for the toddler, who probably can't read yet but whatevs.
"Happy birthday to my little mermaid!" Kourt wrote.
"Seeing the magic in the world through your eyes makes me so happy."
As for Scott, well, he posted a photo of a big white bed plus a couple of selfies today. Awesome.
Kourtney shared a second photo of herself and P, both sporting bikinis while out on a boat in the middle of the ocean somewhere.
The mom of three is vacationing on a tropical island with friends, and while she has not specified where, the pics are most envy-inducing.
Grandma Kris Jenner also wished the tyke a happy birthday on Instagram, sharing a photo of Penelope looking as fashionable as her mom, rocking a top knot, John Lennon sunnies and a crop top.
"Happy birthday to our little princess, my sweet angel girl Penelope!!!!" wrote Kris.
"You bring so much joy to our lives and I love you more than words could ever say!! #sweetgirl #happybirthdaypenelope #myheart"
Last month, InTouch reported that Kourtney was pregnant with her fourth child by Scott and suggested that the new bun might bring the former couple back together.
We're really hoping it's not true, but it's Kourtney and Scott, so anything is possible.
Last month, Penelope had a joint mermaid-themed birthday party with her cousin North West, and more cuteness ensued.
