Jamie Lynn Spears took another step toward marriage and motherhood Thursday – registering for gifts at Babies R Us.

Spears, who turns 17 on April 4th, drove 80 miles to Baton Rouge from her home at the Serenity mansion in Kentwood, La., was reportedly accompanied by her cousin, and, “somebody called ahead to say they were coming in,” claims a source.

Reportedly flashing an engagement ring on her left hand, Spears also was sporting a shirt that read “The Rumors Are True” as she and her cousin both registered for gifts at the store, according to sources.

Casey Aldridge, 18, the baby’s father, is listed as her “co-registrant” and the “event date” listed is July 10. Spears added the message: “Thank you for supporting us during this special time.”
