Scott Disick missed his only daughter, Penelope's birthday party after breaking up with his girlfriend for almost 10 years, Kourtney Kardashian.

On Wednesday, July 8, Disick was in Boca Raton, Florida while his family celebrated his kid's third birthday at Disneyland. Scott expressed his melancholy over him not present at Penelope's special day posting a collage photo of Penelope's paparazzi shots.

"1 of the only things I'm proud off about myself. Happybdayp," he wrote on Instagram.

This came after his two consecutive posts which were slammed by fans - a picture of a car with a caption, "need this asap" on the day of his daughter's birthday, and an invitation to party with him in Las Vegas' 1OAK on July 10, Friday. He then deleted his party invitation.

The controversial reality star just ruined his family life after being snapped partying and canoodling with his ex-girlfriend, 25-year-old Chloe Bartoli, during the 4th of July holiday weekend in France.

Scott and Kourtney then called it quits following the release of his "cheating" photos, which reportedly "humiliated" Kourtney.

At the happiest place on Earth, Kourtney and Penelope were both in Tinkerbell costumes, enjoying the rides with P's cousin, North West and Kim Kardashian. Kanye West's daughter and wife were also wearing matching shirts with "Yeezus" prints.

Also at Penelope's birthday party were her 5-year-old brother, Mason, grandma Kris Jenner, grandma's boyfriend, Corey Gamble, and other family friends.

"Happy birthday to the sweetest little girl in the world. Watching your every little move everyday brings me immeasurable happiness," Kourtney posted on Instagram on Thursday with a hashtag, "toomuchfunyesterdaytopost".

Kourtney also posted their picture with Kim and North, saying her sister was the "MVP" for "hanging with my crazy Disney obsessed self for 12 hours of major madness."

North West, who just turned two in mid-June also celebrated her birthday at Disneyland.
