Jamie Lynn Spears' Boyfriend/Baby Daddy Stable After Accident

Casey Aldridge, Jamie Lynn Spears' boyfriend and baby daddy, is in stable condition after a terrible car crash early Sunday morning.

The 19-year-old Aldridge was driving in his Ford F-150 truck around 1:30 a.m. when he apparently lost control. He and two male friends were returning home from a fishing trip.

According to reports, Aldridge cracked his skull. One pal suffered a broken collarbone.

Sheriff officials in Tensas Parish, La., said that a single-car crash occurred in their area, however, they would not provide any further information. Meanwhile, a representative at Riverland Medical Facility in Ferriday, La., confirmed that Aldridge was treated earlier at their facility, but that "he is not here now."

Spears, 18, has been spotted at the University of Mississippi Medical Center in Jackson, where Aldridge has presumably been transferred.

The couple, who are engaged to be married but haven't set a date, have a 10-month-old daughter, Maddie.
