KARDASHIAN fans have shared their “sad” theory about why Kourtney has been reportedly “deleting and posting” photos of her daughter Penelope’s 10th birthday.

Kourtney, 43, recently uploaded more Instagram snapshots from her daughter’s pool party.

The series kickstarted with Penelope taking out the candles from her birthday cake.

The Kardashians star took a close-up shot of the pink bowl with the word “Love” on the side and the heart-shaped cookies.

Kourtney showed off her bikini body as she pulled the strings of the heart-shaped balloons.

The series closed with a heart-shaped cookie cake that said: “Happy Birthday, Penelope.”

Kourtney wrote: “A dreamy 10th birthday for dream daughter.

“I love letting my kids lead the way when it comes to celebrating their birthdays. She told me all of her ideas and I helped her bring them to life.

She concluded: “For all of the pictures and details go to @poosh.”

The Hulu star also thanked Chef K for “all of the yummy food” and the “extra special vegan and a gluten-free section for me.”

During the pool party, guests were given pink candies in jars and swirly, heart-shaped lollipops.

There was also a huge tropical-style slide that curved into the water and palm trees by the pool.

THE FAN THEORY

Keeping Up With The Kardashians fans theorized that the Poosh founder was using her daughter’s special day in order to capitalize on her website.

One critic claimed: “Honestly, it’s kinda sad that she has no shame in trying to capitalize on Penelope’s birthday party.”

Another critic added: “Wow! Advertising on your 𝚋𝚊𝚋𝚢’s birthday”

A third critic mentioned: “Attempting to drive traffic to Poosh.”

A fourth person chimed in: “She cares more about her financial aesthetic than Penelope’s birthday.”

‘IT’S A PARTY’

Kourtney was not the only parent celebrating her daughter’s tenth birthday.

Her ex, Scott Disick, 39, held a spa sleepover party for Penelope and her guests, which included her siblings and Kim Kardashian’s daughter, North, nine.

The birthday girl was getting her nails done while her brothers Reign, seven, and Mason, 12, were caught roughhousing.

Scott shared snaps from the spa sleepover and captioned the post: “It’s a party. It’s a party, yeah.”

Mason chased after his little brother across the hallway and tackled him to the floor.

Scott screamed out: “How are ya buddy?” while Reigh and Mason continued their high-jinks.

The KUWTK star also promoted the customized white pajamas he and Reign received from Morgan Lane.

Back in May, Kourtney moved on and got married to Travis Barker, 46, at a beautiful ceremony in Portofino, Italy.

The E! star is the stepmother to Travis’ two teenage kids: Alabama, 16, and Landon, 18.
