Britney Spears' Sons Sean Preston & Jayden James Seen Out on Grocery Run

"Circus" in Aisle 5! Britney Spears' boys, Sean Preston and Jayden James Federline, were snapped running errands in a rare public outing together ... and look how they've grown!

Sean, 20, and Jayden, 19, were seen out in Calabasas, California, yesterday ... walking out of an Erewhon with groceries -- and Jayden's alleged girlfriend, who nursed a smoothie.

The boys were largely estranged from their famous mom during their teen years while they lived with their dad, Kevin Federline. But in recent years, they've had more of a connection.

Britney reunited with Jayden on Christmas in 2024 and has shared videos of subsequent meetings since then.

The last time we got a Britney video with her kids, she was riding shotgun with Jayden for a mother-son joyride.
