Jamie Lynn Spears marries fiancé James Watson in Louisiana wedding

Jamie Lynn Spears walked down the aisle with her fiancé James Watson in her home state of Louisiana on Friday.

The ceremony took place at Audubon Tea Room in New Orleans, a source told E! News. Approximately 150-200 guests were in attendance, including her big sis, pop princess Britney. Britney and boyfriend David Lucado were seen catching a flight from Los Angeles to the big event with the 32-year-old incognito in navy sweatpants and a gray sweatshirt.

In preparation for the wedding, the bride-to-be was spotted at a nail salon with mom, Lynne Spears, near their hometown of Kentwood early Friday morning. Jamie Lynn, 22, was casual, sporting a red sweatshirt and shorts as the last wedding preparations were being made.

The bride had her gown, by Liancarlo, picked out since January when she went wedding dress shopping with her 4-year-old daughter Maddie and mom Lynne. After the shopping spree at the I Do Bridal Couture boutique in Baton Rouge, the country singer shared her excitement with her Twitter followers.

"Finally found my perfect dress at @idobridalcouture!!!!!" she tweeted at the time. "Thank y'all so much for making me feel so special and being so accommodating!!!!"

Maddie walked down the aisle as the adorable flower girl in a sparkly white dress, and her cousins Jayden James and Sean, Britney's two boys, were the handsome ring bearers.

The former "Zooey 101" star released the news of her engagement to 31-year-old Watson in March 2013. Jamie Lynn had previously been engaged to her daughter's father, Casey Aldridge, before they ended their relationship four years ago. Jamie Lynn became pregnant at age 16 with Maddie while still on Nickelodeon's "Zooey 101."

It seems marriage is on the agenda first before any talk of future children, and her family, especially Britney, couldn't be happier.

She tweeted: "So excited and happy for my sister! congrats @jamielynn spears - love you."
