Kourtney Kardashian has celebrated her son's birthday at Disneyland.
The reality TV star donned a pair of golden Mickey Mouse ears while walking around the theme park in Anaheim, California, with her son Mason - who turns four on Saturday (12.14.13) - and 17-month-old daughter Penelope.
Although Kourtney's long-time partner Scott Disick - who she has been in a relationship since 2006 - didn't join his girlfriend on kids on the family trip, Kourtney was joined by a friend.
Kourtney, 34, kept her big ears on while riding with Penelope on the Fantasyland carousel and wore a long-sleeved Snow White T-shirt.
Kourtney was clearly excited about the trip and also posted a photograph on her Instagram account with a friend along with the message: "Mason's birthday week!!! We're at Disneyland!!! Ahhh!!! #BFFlife #Mommylife #disneyland. [sic]"
She started the day by sharing a snap of her in a pair of Mickey Mouse printed Rayban sunglasses and also posted a photograph of the family's ride through 'It's A Small World'.
Kourtney and her children stopped by the Haunted Mansion before enjoying the fireworks display and fake snow fall at Princess Aurora's castle at the wondrous attraction.
