It's official, y'all! Jamie Lynn Spears and her fiance Jamie Watson have obtained their wedding license. The aspiring country singer and her beau have been engaged for one year.

The couple of four years obtained their license from Tangipahoa Parish Clerk of Court in Louisiana on March 5. So, what is their wedding date? The adorable pair will be tying the knot (tomorrow!) on Friday, March 14. (E! was first to report the news.)

Spears, 22, announced back in March 2013 that Watson, 31, popped the question. "Guesssss what??????" she tweeted at the time, alongside a picture of her gorgeous diamond ring. She later added: "He did good."

This will be the first marriage for Britney Spears' younger sister. The "How Could I Want More" singer was previously engaged to Casey Aldridge. They later split in 2010 and are parents to 5-year-old daughter, Maddie.
