Video: Britney Spears Kicks Off Femme Fatale Tour in Sacramento

Billboard Bits: Britney Spears Has In-Home Club, Neutral Milk Hotel Boxset On the Way

Britney Spears made her long-awaited arena return when her Femme Fatale tour kicked off at the Power Balance Pavilion in Sacramento, Calif., on Thursday (June 16). A slew of fan videos recorded last night capture the pop star running through her stacked back catalogue, along with new hits like "Hold It Against Me" and "I Wanna Go."

In this fan-shot video, Spears can be seen leaning on the front wheel of a motorcycle and singing "...Baby One More Time" as leather-clad male dancers perform backflips and tumbles around her. After performing a quick slow-dance with one of her dancers, she shoves him to the ground, and soon the backing track morphs into the Spears-assisted remix of Rihanna's "S&M."

Britney Spears' 'I Wanna Go' Video to Premiere Next Wednesday

The next clip shows Spears leading a fist-pump session as her fans sing along to her latest single, "I Wanna Go." A couple of lucky Britney worshippers even got to join the singer onstage and pose for a few photos.

Spears slowed things down and took a seat on a giant metallic swing for "Don't Let Me Be the Last to Know." Halfway through the track, a shirtless male acrobat hangs from a harness attached to the bottom of the swing, with Spears still belting out the ballad.

"Hold It Against Me," the lead single to "Femme Fatale," was also given a flashy set piece, with Spears leading a massive sing-along while performing dance moves in a silver two-piece next to some light-footed police officers. The pop star gets locked in a faux-jail cell and soon begins singing "Up N Down."

Of course, "Till the World Ends" wouldn't have felt right without tour opener Nicki Minaj getting in on the fun: the rapper's opening verse of the remix to the hit single was shown on a giant screen, while Spears danced around in a sleek black outfit.

After the Sacramento show wrapped, Spears posted on Twitter, "Can't sleep. WAY too much Adrenaline right now. Sacramento was on fire tonight. You ready San Jose? Cause I am!!!!" The Femme Fatale tour continues Saturday at San Jose, Calif.'s HP Pavilion, and ends its U.S. run on Aug. 25 before heading to Europe in September.

Nearly three months after "Femme Fatale" debuted at No. 1 on the Billboard 200, "Till the World Ends," holds at No. 12 on this week's Hot 100. Meanwhile, the official music video for "I Wanna Go" will make its MTV premiere on Wednesday (June 22), just in time to qualify for this year's Video Music Awards.
