Jaime Lynn Spears and Casey Aldridge Call It Quits!

Younger sister of Britney Spears, Jaime Lynn and partner Casey Aldridge have called it quits. Spears and Aldridge had planned to marry but the couple pulled of their engagement. But the two remained as couple living with their child, Maddie, in a Liberty, Miss., home.

According to reports, the two separated because, "She did a lot of growing up but he didn't," a source told the mag of Aldridge. "I think she put up with more than she cared to put up with. She just got enough of it and was tired of the situation." The former "Zoey 101" actress has also reportedly moved back in with her mom, Lynne.

The 18-year-old star Spears has already moved on - she's reportedly dating businessman James Watson. Watson, on the other hand, is 28, 10 years older than Jamie Lynn.
