Casey Aldridge, the boyfriend of Jamie Lynn Spears
and father to her 10-month-old baby, was released from a Mississippi hospital on Friday, five days after flipping over in his pickup truck
while partying with friends at a late-night bachelor party, a family source tells PEOPLE.
"Casey got home today, and he's doing really well," the source says. "He'll have to have some rest for the next few weeks. He's still got a headache, but everything looks good."
Aldridge, 20, suffered a head injury that required no surgery and apparently caused no permanent damage, the source says. He was taken to a small, rural hospital in Ferriday, La., early Sunday and later transferred by ambulance to the larger University of Mississippi Medical Center in Jackson, where he spent time in the intensive care unit
Spears has been at his side since the incident, even riding in the ambulance with Aldridge on the way to the Mississippi hospital.
"They're both at the house in Liberty (Miss.)," the source says. Spears's mother, Lynne, has been keeping the couple's baby, Maddie Briann, "for most of the time during this whole episode, but I guess the baby will be going back home. Now Jamie Lynn will have two babies to care for."
Aldridge had been attending a bachelor party for a cousin who is getting married next week. He is the best man, "but I don't know if he'll be up to that or not. We'll just have to wait and see," the source says.
