Less than two weeks after being thrown from his pickup after a late-night bachelor party, Jamie Lynn Spears‘s boyfriend, Casey Aldridge, stood as best man at his cousin’s weekend wedding in Mississippi, a family source tells PEOPLE.
“He had the weakness of having been in bed and still trying to get his feet under him, but he made it,” the source says. “It was outside, it was hot, but he did okay. It’s just going to take him a few weeks to get better.”
The wedding and reception took place Saturday at Luckett Lodge in Brandon, Miss., with about 50 guests. Another source says Casey was limping and walking slowly. “He was not very animated,” that source said. “He is usually quite lively, but he seemed lethargic.”
Spears also participated in the wedding but was not part of the wedding party. “She helped greet guests,” the family source says. “No one really made a big deal over her, it was just Casey and Jamie Lynn.”
Aldridge, 20, flipped his truck on April 26 on a rural Louisiana road, causing him and two of his four passengers to be thrown from the vehicle. Aldridge spent nearly a week in the hospital with head trauma but no apparent brain injury.
As for wedding bells ringing in the future for Aldridge and Spears, the family source says there are no concrete plans, “but they’re definitely together. You can throw all those rumors away.” He and Spears are living together with their 11-month-old daughter, Maddie.
While Aldridge appears ready to recover fully from the wreck, the hospital stay and trauma of his narrow escape from serious injury may have had an effect on him, the source says. “He seems to me to be thinking a little more seriously about things,” the family source says. “I think he seems to be a little more subdued, more down to earth.”
