Watch Britney Spears Throw it Back to All Her Greatest Hits

Britney Spears hit the stage of the iHeartRadio Music Festival in Las Vegas on Saturday, giving a classic performance of many of her most popular songs with some fiery peak Britney choreography. (And yes, there was lots of bare midriff on display, as is her signature.)

More recent classics like “Work, B***h” made the set list, alongside newer releases like “Do You Wanna Come Over” and crowd favorites like “I’m A Slave 4 U” and the timeless “Toxic.” Backed up by a crew of well-rehearsed dancers, the “Glory” star shimmied, strutted, and flipped her hair (worn in pigtails — throwback to “Baby One More Time,” anyone?) as she worked her way through her musical oeuvre. And it looks like her recent dancing classes have paid off, as the full twenty-plus-minute set was neatly choreographed to take advantage of her iconic onstage sass. Vegas, it seems, brings out the best in her.
