It looks like Kourtney Kardashian isn't going to let her breakup drama with longtime boyfriend Scott Disick get in the way of having a fun-filled day with her kids at the Happiest Place on Earth!

On Wednesday, their daughter Penelope turned 3, and Kourtney, her sister Kim and Kim's daughter North West all went to Disneyland to celebrate the big day, despite what's been going on between Kourtney and Scott these past few days. Penelope's older brother Mason, little sister Reign, grandma Kris Jenner and Kris' boyfriend Corey Gamble were all in attendance too, along with some other family friends. But Scott was noticeably nowhere in sight, according to Us Weekly.

Penelope and Kourtney wore matching Tinkerbell costumes and looked cuter than ever. Kourtney shared a few photos of the special day to her Instagram.

The first showed Penelope in her costume and French braid pigtails with a giant ice cream sundae. "Happy birthday to the sweetest little girl in the world," Kourtney wrote. "Watching your every little move every day brings me immeasurable happiness. #toomuchfunyesterdaytopost #disneyland."

The next adorable photo of Penelope had another heartfelt caption. "You forever changed my life and my heart and teach me so much every day," it read. "Happy birthday to my tinkerbell angel."

Another showed Kourtney's matching costume as they stood alongside Disney's very own Tinkerbell. "I bet you didn't know there were three tinkerbells. #disneyland," this caption read.

Although he was still in Florida during the celebration, Disick did share a rather depressing Instagram post of his own to say happy birthday to his daughter. He put together a collage of photos of Penelope and wrote, "1 of the only things I'm proud of about myself. Happybdayp."

It's no surprise that the family decided on Disneyland to celebrate her birthday. Last month, Kim and her husband Kanye West rented out Disneyland for their daughter North's second birthday . Kim posted several photos of the two cousins hugging and smiling in honor of Penelope's birthday. "Thanks for being the best big cousin North always looks up to!" one of the captions read.

North and Penelope are constantly seen having such a fun time together and it's great that the cousins got to celebrate their birthdays not only together, but in the same, magical place.

 1 of the only things I'm proud off about myself. Happybdayp
