People magazine reports that Bryan, 31, got hitched to 36-year-old Sanchez at New Orleans landmark building Latrobe's on Royal on December 31. Though the two had only been dating seriously for a short time, they have much in common: Sanchez has been a long-time manager to Bryan's 17-year-old sister, Jamie Lynn Spears.

Most of the Spears clan—including Britney, 26, Jamie Lynn, and their collective offspring, Jayden James, Sean Preston and Maddie—were in attendance for the ceremony, along with Jamie Lynn's fiancé, Casey Aldridge. Sanchez's mother and brother were also present.

The bride wore a beige-white Carolina Herrera dress for the occasion, while Bryan said goodbye to the single life in a Marc Jacobs suit.

"It was beautiful," a source says of the nuptials. "It was only close family, very small and intimate."

A Spears family friend adds, "The family was totally excited. Graciella's wonderful. Everybody was happy about it."
