Jennifer Lopez was stripped of her pop diva glamour Monday as she sported a blue ‘Value Shop’ vest during her first day of filming Second Act at a Queens supermarket.

The 48-year-old Golden Globe nominee was ‘here to help’ as Maya, a Costco-style employee who ‘reinvents her life to show Madison Avenue what street smarts can do.’

The Bronx-born beauty gave her blondette bob a big boost with hair extensions and she rocked hoop earrings while larking around with her real-life best friend Leah Remini, 47, on the Astoria set.
