"It was beautiful," a source tells PEOPLE about the elder Spears's wedding to Graciella Sanchez, 36, longtime manager of little sister Jamie Lynn
. "It was only close family, very small and intimate."
While the couple's engagement

"The family was totally excited," a friend of the family tells PEOPLE. "Graciella's wonderful. Everybody was happy about it."
The bride looked stunning in a beige-white Carolina Herrera dress, while the groom sported a smart Marc Jacobs suit. As for the guests? Sanchez's mother and brother were in attendance, as was the entire Spears crew including sisters Britney and Jamie Lynn; their kids Jayden James, Preston and Maddie; Jamie Lynn's fiancé Casey Aldridge; and parents Jamie and Lynne.
