Britney Spears is getting back to business. This week marks the start of the 34-year-old’s New Year's run of her residency at the Planet Hollywood Resort and Casino in Las Vegas and the legendary pop superstar commemorated her post-holiday return to Sin City with a couple cute family photos.

The “Toxic” singer shared two snaps of her darling (and almost identical!) sons—Sean Preston, 10, and Jayden James, 9, (dad is Spears’s ex-husband, Kevin Federline)—on Instagram. Both boys rock side-swept hair while Mom dons a tan hat in the images. In Spears's first post, the children show off adorable toothy grins:

In the second family photo, Sean Preston stands tall with a more serious look on his face:

Spears also posted an adorable candid shot of herself to mark her return to her Britney: Piece of Me show. “Back in Vegas peeps!” she wrote in the caption:

The show goes on hiatus starting Jan. 3, 2016, during which time Spears reportedly plans to revamp and redesign her performances and Jennifer Lopez's residency kicks off at Planet Hollywood's Axis Theater. Lopez's first run wraps up Feb. 9 while Britney: Piece of Me returns to the Axis on Feb 13.
