WASHINGTON — After a long hiatus, pop star Gwen Stefani is back on tour promoting her latest album, “This Is What the Truth Feels Like.”

Stefani took the stage Sunday night at Jiffy Lube Live in Bristow, Virginia, marking the third stop on her new tour, declaring the audience the “best yet.”

While the focus was certainly her new music, she didn’t shy away from singing a slew of fan favorites from both her solo career (“Hollaback Girl,” “Rich Girl,” “Sweet Escape”) and from her days with No Doubt (“Don’t Speak,” “I’m Just a Girl,” “It’s My Life”).

Her “Voice” colleague and boyfriend Blake Shelton made a surprise appearance, as the two sang a sweet duet on stage with “Go Ahead and Break My Heart.”

Hip-hop star Eve opened the show, then returned to join Stefani for “Let Me Blow Your Mind.”
