Center stage, a spotlight, a microphone … and another singing Spears.
Jamie Lynn Spears, 20, took to a Nashville stage for the first time on Monday night, singing a set of her own original songs to a packed crowd of family and friends.
Grandfather June Spears traveled from the family’s hometown of Kentwood, La., with other relatives (although not sister Britney Spears, who is touring overseas) to cheer on Jamie Lynn, sitting near her beaming parents Lynne and Jamie Spears, as well as country music legend Pam Tillis.
“I am so emotional tonight,” Lynne told PEOPLE after watching her youngest daughter perform. Her father, Jamie, concurred, saying, “We are so proud of her.”
Spears, who has been living in Nashville the past two years with her daughter, Maddie, 3, performed at The Rutledge, a live music venue on 4th Avenue South and took to Twitter to express her appreciation.
“Just wanna thank all my amazing friends and family for coming out tonight!!!” she wrote.
