Britney Spears' sons, Preston and Jayden, had a sweet reunion with Jamie Lynn Spears' daughters, Maddie and Ivey. "Senior night," Maddie wrote via Instagram on Wednesday, September 17, alongside several photos from a game with her high school softball team. Maddie posed with her fellow senior classmates in their uniforms. Maddie also wore a sling on her right arm after tearing her shoulder labrum earlier this year. In addition to taking pictures with friends, Maddie was joined by her family. She smiled for a sweet snap with her mom, stepdad Jamie Watson and sister Ivey, 7, on the field.
