Boyfriend of two years (and her former agent) Jason Trawick was at her side backstage, giving the costumed Spears an apparent good luck-hug in a photo she Tweeted before dominating the Power Balance Pavilion.
"It's Opening Night B–––!" she wrote.
Spears, 29, launched the show with her hit, "Hold It Against Me," bringing the glitz and the glam in her Zaldy Goco-designed ensembles.
"Can't sleep," she Tweeted after the show. "WAY too much Adrenaline right now. Sacramento was on fire tonight."
Critics seemed to share her excitement about the tour, which hits San Jose, Calif., Saturday night. "The night belonged to Britney," a Rolling Stone review read. Calling it her flashiest show yet, the report continued: "The pop star whose career seemed in danger of ending just a couple years ago has shown that she's back – hopefully this time to stay."
