Jamie Lynn Spears, the younger sister of pop music legend Britney Spears, has reportedly gone country. On Monday, the 20-year-old Nashville resident made her stage debut at the Rutledge in front of a crowd made up of her family, friends and country music's own Pam Tillis.

Even Jamie Lynn's grandfather, June Spears, traveled to Tennessee from the family's hometown of Kentwood, La. to see his granddaughter perform for the first time. Jamie Lynn's mother, Lynn, told PEOPLE, "I am so emotional tonight," while her father, Jamie, chimed in, "We are so proud of her."

Jamie Lynn delivered a set of original songs, and later took to Twitter to thank her growing, albeit small, fanbase for their support. "Just wanna thank all my amazing friends and family for coming out tonight!!!! #feelingthelove," she said. The younger Spears and her 3-year-old daughter, Maddie, have called Nashville home for two years.

While Britney Spears could not attend the gig -- as she's touring her seventh chart-topping album, 'Femme Fatale,' overseas -- she did have a few words for her sister. Britney tweeted, "Heard you were amazing sis. Love you!!"

There's no word on plans for more live performances or a country album from Jamie Lynn Spears at this time, but it sounds like she'll have support if she pursues a career in music.
