ATV Accident Badly Injures Jamie Lynn Spears' Daughter

"All I can say is pray for our baby Maddie." That's what Jamie Spears, dad of Britney and Jamie Lynn, told Entertainment Tonight following reports that his 8-year-old granddaughter had been seriously injured in an ATV accident Sunday. TMZ first reported on the incident, which reportedly took place in or near Kentwood, La., where sources tell the site that Maddie Aldridge, the daughter of Jamie Lynn, was riding a Polaris off-road vehicle when it overturned. The girl reportedly remained unconscious underwater for a few minutes and is said by TMZ to be in "extremely serious" condition. An airlift reportedly transported Maddie to a local hospital.

TMZ reports that Maddie was part of a hunting trip and that Jamie Lynn, the 25-year-old former star of Nickelodeon's Zoey 101 and Britney's younger sister, wasn't with her daughter. A Spears rep, however, tells ET that details swirling about Maddie's accident are "incorrect" and asks the public to allow the Spears family its privacy. Jamie Lynn made headlines when she became pregnant with Maddie at the age of 16 with Casey Aldridge, who was then her beau, Us Weekly notes. Jamie Lynn has since married Jamie Watson, who she told ET last June was "very strict on most everything" of what Maddie is and isn't allowed to do. (Jamie Lynn is a singer like her sister, but in the country vein.)
