“Sunday funday at @unistudios with the family!” the single mom, 33, captioned the image with her sons Preston, 10, and Jayden, 9, and her big brother Bryan, 38, and his daughter Lexie.
The group enjoyed an action-packed day at Universal Studios Hollywood.
Auntie Britney also shared a shot with her niece. “Hiii from me and Lexie,” Britney captioned the pre-ride snap.
The duo scope out the park’s views while riding high in a video she also shared.
In recent months, Lexie has become a familiar face on Britney’s social media accounts. Over the summer, the singer and Lexie were seen enjoying some one-on-one time together, and at the Teen Choice Awards.
