Asghari shared the same photo along with the caption "Happiest man on earth @disneyland."
It looks like Spears and her crew hit up several attractions. The "Piece of Me" singer took a photo of the kids in front of the Sailing Ship Columbia at Frontierland within the Disneyland Park and snapped a pic of the group in front of the classic Mickey Mouse floral arrangement. The Daily Mail also shared photos of Spears and the boys riding the Radiator Springs Racers ride in Cars Land at Disney California Adventure. So, it looks like the birthday group purchased the Park Hopper option to be able to move from one park to the next easily.

Throwing a party at Disneyland may be tough to beat, but Spears knows how to celebrate birthdays in style. Last year, she threw a Pokémon-themed party for her boys. We hope we get an invite to next year's celebration.
