Capping off a year of setbacks, comebacks, and a new bundle of joy, the Spears family has another surprise in store – a wedding!

Britney Spears‘s big brother, Bryan Spears, 31, is newly engaged to Graciella Sanchez, 36, and the pair plan to wed soon – possibly over the New Year’s holiday, sources tell PEOPLE.

The couple have been acquaintances for years, but only recently started dating seriously. Sanchez is the manager for Bryan’s little sister Jamie Lynn.

A Yale graduate, Sanchez helped found One Talent Management, where she still works. Bryan Spears is a producer with credits including Jamie Lynn’s star-making vehicle Zoey 101.

Britney, 27, who flew to Louisiana on Sunday with her two sons Jayden James, 3, and Preston, 2, is expected to attend the nuptials.
