We hope she's OK!

Jamie Lynn Spears' daughter Maddie was seriously injured in an ATV accident on Sunday, and it was so bad she was airlifted to a local hospital in Louisiana, TMZ reports.

The 8-year-old was riding the vehicle on a hunting expedition when it flipped over, and she was submerged under water for several minutes while unconscious. Her mom was 100 yards away at the time, and rushed to free her from the safety belt but was unable to do so.

Britney Spears' dad confirmed the sad news and asked people for prayers. "All I can say is pray for our baby Maddie,” he told Entertainment Tonight.

She's in our thoughts!
