Britney Spears threw a video game-themed birthday party last Saturday for her boys to celebrate Preston, who turned 7 on Sept. 14, and Jayden, who turned 6 on Sept. 12.
“The whole family had a great time,” a source close to Spears tells PEOPLE of the afternoon bash held at Sky High Sports, an indoor trampoline park in Woodland Hills, Calif.
“Britney really enjoyed herself,” adds the source of Spears, who at one point hopped on the trampolines herself to jump around with niece Maddie, 4, and played video games in Sky High’s arcade.
