Jamie Lynn Spears is all ready to make it official.
Britney Spears' 22-year-old sister and fiancé James Watson have obtained a marriage license from Tangipahoa Parish Clerk of Courts in their native Louisiana, E! News confirmed Thursday.
And a source tells us that they will be tying the knot on Friday—as in tomorrow!
The couple, who've been engaged for a year, filed for the license on March 5. In the state of Louisiana, there is a 72-hour waiting period from when the license is issued and when the ceremony can take place, and in any parish the license is good for 30 days after issuance.
"#hedidgood," the bride-to-be tweeted about the dazzling diamond ring Watson gave her.
They've been pretty quiet about their actual nuptial plans, but the groom posted an Instagram pic of the Vegas skyline over the weekend—taken during his bachelor party, perhaps?
In another clue that her big day was just around the corner, Spears shared a pic while shopping for wedding dresses in January, teasing that she had found the "perfect" dress. I Do Bridal Couture later shared that she had opted for a gown by Liancarlo.
This will be the first marriage for Spears, who was engaged to but never swapped vows with her 4 1/2-year-old daughter Maddie's father, Casey Aldridge. They broke up for good in 2010.
After taking time off to be a full-time mom, Jamie Lynn has been easing back into recording and touring, releasing the single "How Could I Want More" in November and appearing with her big sis on the Britney Jean track "Chillin' With You."
