Kourtney Kardashian and Scott Disick celebrated their sons' birthdays at the happiest place on Earth!
Mason, 7, and Reign, 2 -- who were born five years apart on Dec. 14 -- were treated to a fun-filled day at Disneyland in Anaheim, California, on Wednesday. Their grandmother, Kris Jenner, was also in attendance, as well as their sister, 4-year-old Penelope, and cousin, 3-year-old North West, an eyewitness tells ET.
Inside the theme park, birthday boys Mason and Reign got an extra special treat -- a tray of chocolate cupcakes with red frosting and an assortment of Mickey Mouse balloons, as Kourtney documented via Snapchat.
According to the eyewitness, who spotted the group standing in line for the Indiana Jones Adventure ride, "all of the kids looked happy and excited to be there."
"Kris looked happy to be spending time with the kids," the eyewitness added. "Kourtney and Scott looked a little irritated, but it could just be because they were tired -- definitely no romance or cuteness between the two of them."
