Wedding Bells for Jamie Lynn Spears and Casey Aldridge?

This week’s print edition of In Touch is running a story noting that Jamie Lynn Spears, younger sister to pop queen Britney Spears, is moving ahead with plans to marry Casey Aldridge.

MSNBC reports that Jamie Lynn has selected a Monique Lhuillier gown, ordered invitations and chosen a three-tiered chocolate cake for her big day.

Spears, 17, and Aldridge, 19, have been in the spotlight for over a year now, since the world learned the two teens were expecting a child together in December 2007.

The youngest of the Spears siblings gave birth to Maddie Briann Aldridge on June 19, 2008.

Perhaps Jamie Lynn was moved to finally tie the knot with Casey after her brother, Bryan Spears, 31, married Graciella Sanchez, on New Year’s Eve.

The entire Spears family was in attendance for Bryan’s nuptials, but Jamie Lynn has a particular connection with new sister-in-law Sanchez; Graciella, 36, is the former Zoey 101 star’s manager.

And if the wedding reports are true, sometime soon, Britney—who has been married twice now—will be the only one of the Spears clan to remain single.
