The couple announced plans to wed before calling off the engagement and splitting earlier this year (10), but was reported to have reunited in August (10) after attending a Lady Gaga concert together.
However, Jamie Lynn Spears has ended her relationship with 21-year-old Casey Aldridge once again, according to America's Star magazine.
A source tells the publication, "Jamie Lynn got fed up with Casey's immature behaviour. She thought he'd changed - that's why she got back together with him. But he's still the same old guy."
