Jamie Lynn Spears brought two-month-old daughter Maddie to Los Angeles Wednesday for the baby's first ever play date with Britney's two sons.

The 17-year-old flew from Louisiana – along with her baby and her mother Lynne (whose memoir comes out next week). The whole family then headed to Britney's Studio City house, where the singer was enjoying a regular visitation day with her two boys, Preston, who turns 3 on Sunday, and Jayden, who turns 2 on Friday.

Britney’s ex, Kevin Federline, came to pick up his sons himself, and stayed for about an hour to take part in the reunion.
