It was a Spears family reunion last night in Nashville.

Before Jamie Lynn took the stage to perform, she received a delightful surprise in the form of an appearance and introduction from her big sister Britney and brother Mark. Britney was clearly proud of her little sister, and the emotions spilled out during her introduction.

"Thanks to the Opry for letting me introduce this beautiful, young lady who is my heart and my soul," Britney said. "Not only is she beautiful and extremely talented, she's my little sister...Jamie Lynn Spears!"

It was a touching moment that clearly came as a genuine surprise to Jamie Lynn, who tried admirably to hold back her tears to no avail.

It's nice to know that even in the world of celebrity, family always has your back.
