It's Penelope Disick's 7th birthday and her mum, Kourtney Kardashian is making sure it's a memorable one.

The only daughter of Kourtney and Lord Disick celebrated with her Kardashian cousins and friends. It was a pajama party which held at an IHOP (International House of Pancakes) in Calabasas.

They kicked things off with a stretch limousine ride to the venue of the party where the girls and Kourtney were then seen disembarking from the Mercedes Benz G-Wagen limousine, all of them in their PJs.
