Ke$ha Brings a 'Full Moon' to "The Immortal" Tour

It made its Los Angeles debut the previous night, and Ke$ha ventured out to see Michael Jackson "The Immortal" World Tour by Cirque du Soleil at the Staples Center on Saturday (January 28).

The "We R Who We R" hitmaker strolled past paparazzi upon hitting the entrance as her friends put on a show for the shutterbugs with one of Ke$ha's gal pals classily mooning the cameras.

Also turning up for the stage show celebrating the life of the King of Pop were recently married couple, Nick and Vanessa Lachey.

Rounding out the stars in attendance at day two of the Staples Center run was "Cougar Town" actress Courteney Cox, who brought along daughter Coco for the MJ tribute.

Enjoy the pictures of Ke$ha, Vanessa Minnillo, Nick Lachey and Courteney Cox at Cirque du Soleil at the Staples Center in Los Angeles (January 28).
