Casey Aldridge, the father of Jamie Lynn-Spears’ 8-month-old daughter, is in a Jackson, Mississippi hospital after a bad car wreck last night. Jamie Lynn is at his side. Aldridge was driving home at 1:30 a.m. Sunday when he wrecked his Ford F150 with two male pals in the car, one of whom broke his collar bone. The source adds that Casey has a hematoma and doctors fear he has a blood clot in his brain. He may be heading into surgery.

Aldridge, 19, is a Mississippi native and longtime boyfriend of Britney Spears’ younger sister.
