Jamie Lynn Spears has split from Casey Aldridge, with whom she has a 19-month-old daughter, UsMagazine.com has learned.

The younger sister of Britney Spears, star of Nickelodeon's hit Zoey 101, made headlines in 2007 when she announced that she was pregnant at the age of 16.

A year later, rumors spread that she and Aldridge, now 20, were engaged after she began wearing a diamond ring. Around the same time, she wore a shirt that read, "The Rumors Are True."

Months after her 17th birthday, she gave birth to daughter Maddie Briann in June 2008 at a hospital in Mississippi, near her Kentwood, La., hometown, where she owns a home.

In a 2008 interview, Lynne Spears said she was proud of her daughter but was sad at all the scrutiny she endured.

"Nobody wants their children to have these kinds of hardships or bumps," Lynne said. "Who would want that?"
