Britney Spears and The M&M's showed up at the Los Angeles House of Blues Thursday night on the third and reportedly final stop on her "comeback" tour.

Access Hollywood reports that even some celebrities came out to check out Spears in action. Lindsay Lohan, the Olsen Twins and reggae/dancehall star Sean Paul watched Britney's short performance.

The pop star's show was less than 15 minutes and she even wore a new black wig.

Britney kicked off her whirlwind House of Blues mini-tour earlier this week, performing on Tuesday in San Diego and Wednesday in Anaheim.
