Britney Spears’ younger sister Jamie Lynn has sparked rumors of a reunion with her high school sweetheart — Casey Aldridge — after the young parents were spotted attending a Lady Gaga concert together in Los Angeles last week.
“(They) are working on things between them,” a snoop tells PEOPLE.
The previously-engaged Spears and Aldridge, who welcomed daughter Maddie in June 2008, split in December. Jamie Lynn briefly dated James Watson, a Louisiana businessman in his thirties. But that relationship quickly fizzled out. Casey and Jamie were reportedly spotted together at the Gaga show at the Staples Center last Wednesday night. The young lover’s were accompanied by Jamie Lynn’s older sister Britney and her boyfriend, Jason Trawick.
