Cymphonique gets herself pumped up during the 2011 Worldwide Day of Play held at the Ellipse on Saturday afternoon (September 24) in Washington, D.C.

The 14-year-old Nick starlet joined pals Big Time Rush and new costar Max Schneider on the grass, trying to win for the Green Team.

Cymphonique and Max will star in the upcoming How To Rock, which follows Kacey Simon who forges unlikely friendships with the members of the band Gravity featuring Stevie (Lulu Antariksa), Zander (Schneider) and Nelson (Noah Crawford).

As lead singer, Kacey takes Gravity’s musical success to new heights while igniting a musical rivalry with The Perfs.
