Jamie Lynn Spears' Boyfriend Casey Aldridge On The Mend After Car Crash

Jamie Lynn Spears' boyfriend Casey Aldridge is out of intensive care and on the mend after receiving serious injuries in a car crash on Sunday.

Casey - who shares 10-month-old daughter Maddie with Jamie Lynn - was airlifted to the University of Mississippi Medical Center with head injuries, when his vehicle swerved into a ditch on a Louisiana highway.

Three of the five people riding in the truck, including Casey, were thrown from the vehicle as it flipped over.

Jamie Lynn's beau suffered mild brain trauma and a fractured skull, while another passenger sustained a broken collarbone, and a third injured his hip.

But the 19-year-old has been responding well to treatment and was moved out of intensive care yesterday.

His uncle Odus Jackson tells E! News, "It was a big scare there for a moment, but he got moved out of ICU and is doing good."
