Britney Spears [1]'s sons are all grown up! On Thursday, Britney's 28-year-old sister, Jamie Lynn, shared a photo of her and her nephews, 13-year-old Preston and 12-year-old Jayden, at the Atlanta Braves baseball game. "Everyone had a good time at the @braves game, even JPW🤳🏻⚾️♥️," Jamie captioned a photo of the group FaceTiming her husband, Jamie Watson. The trio were also joined by Jamie's 11-year-old daughter, Maddie [2], whom she shares with ex Casey Aldridge.

Even though Britney was not in attendance, the singer has been focusing on her family since completing treatment at a mental health facility [3] back in April. Most recently, she and boyfriend Sam Asghari made their red carpet debut [4] as a couple at the LA premiere of Once Upon a Time in Hollywood.
