Baby Penelope is ONE already! Where does the time go?

Kourtney Kardashian, 34, and boyfriend Scott Disick, 30, threw their daughter, Penelope, a huge birthday bash last Sunday -- and they went went all out, of course. The guest list included, ohhh, 150 guests, including Kim Kardashian, Kanye West, and their new baby, North West, who was apparently kept away from all the guests (according to Us Weekly). And the venue: Grandma Kris Jenner's home in LA, where Kim, Kanye and the baby are reportedly staying.

Kris's home was transformed into a whimsical garden party filled with massive pink and white balloons.

"Balloon partyyyyy!" Kourtney tweeted, along with photos of the decorations. "Major balloon party, that is!" she clarified, and posted the above photo of herself posing among the humungous balloons.

In addition to the balloons, there were animals -- including a little piglet and a horse dressed as a unicorn.

And in addition to the party, Kourtney and Scott treated Penelope and her brother, Mason, 3, to a day at Disneyland.

"Magical Monday night at my home away from home. #Disneyland #movingin," Kourtney Instagrammed along with this photo of the fireworks.
