Before a raucous crowd that chanted her name, Britney Spears continued her comeback mini-tour Wednesday night, performing the identical lip-synced routine of older hits from her show the night before.

“Thank you so much!” Spears told the audience at the Anaheim, Calif., House of Blues, after finishing her 12-minute set. She acknowledged her backup dancers, blew a kiss and left the stage.

The performance followed her return to the stage Tuesday night at the House of Blues in San Diego after a nearly three-year absence from live performing.

Security was tighter in Anaheim – it took the crowd nearly two hours to get through the metal detectors – with guards seizing cellular phones in an apparent reaction to the flood of pictures and videos of the San Diego show on the Internet.

As the crowd chanted, “Britney! Britney! Britney!” the lights dimmed at about 9:35 p.m. and Spears, wearing a wig over her famously shaved head, launched into “Baby One More Time” in a carbon copy of the San Diego show – down to the at-times bad lip-syncing. At several points, she was seen chewing gum during songs.

Shunning new material, she also performed her hits “Do Somethin’,” “I’m a Save 4 U,” “Breathe on Me” – which featured Spears giving a lap dance to a man brought on stage from the audience – and “Toxic.”

“She was a little off, a little slower than her dancers,” said Kelly Weston of Orange County. “If I hadn’t heard about last night I would probably be disappointed.”

But a group of young women expressed themselves on their tight pink tank tops, which read, “Bald Ambition” on the front and “The Comeback 2007″ on the back.

Spears’s last major performance was in June 2004 during her Onyx Hotel Tour in Dublin, Ireland, which was cut short when she injured her knee.

Spears is also planning several other performances this week, including shows at the Los Angeles House of Blues on Thursday and the House of Blues Las Vegas inside Mandalay Bay on Sunday.
