Sources are claiming that pregnant teen TV actress Jamie Lynn Spears is now engaged, according to People. The 16-year-old's fiancé, Casey Aldridge, 18, reportedly popped the question -- and Jamie's been flaunting a bauble to friends and family. "She's been showing it off, talking about it," the source says.

The "Zoey 101" star and Casey, a construction worker, expect their babe this summer, and Jamie Lynn has said she plans to stay in Louisiana.
