London, Apr 29 : The lover of Britney Spears' younger sister Jamie Lynn Spears was involved in horror car accident when he wrecked his Ford truck after a fishing trip.

Casey Aldridge, 19, suffered a blood clot near his brain after the car crash and the Nickelodeon star was at his bedside before doctors operated on him.

"Jamie and Britney are both worried sick. They're concerned about reports that he may need surgery for a blood clot. At first they thought it wasn't that serious," The Daily Star quoted a source as saying.

Aldridge and two of his four passengers were not wearing seat belts and were catapulted out of the vehicle.

The medics have said that he had suffered mild brain trauma, a fractured skull and had been "in and out of consciousness".

Aldridge has been charged with careless driving on his way home in Mississippi.

Also, Louisiana State Police added that there was no indication of the involvement of alcohol or drugs in the incident.

Casey and his pals had been at a cousin's stag do before deciding to go late night crabbing.

Jamie Lynn, 18, gave birth to Casey's daughter Maddie just 10 months ago and the couple have been living together since then.

However, they have not yet announced any plans to marry. (ANI)
