Ke$ha is back in full force. After making a series of sophisticated style choices in April, the 26-year-old singer returned to her over-the-top roots on the L.A. set of her new "Crazy Kids" music video on May 9.

The glitter-loving pop star shared several behind the scenes pictures via Instagram and Twitter. "Just wait until you see what these super sweet biker dudes are doing in my video," she wrote in one caption.

Wearing an embellished blue hoodie, gold chains and kooky glasses, Ke$ha rocked purple and blue cornrows for the shoot. "Crazy Kids" serves as the third single from the album Warrior, released in November 2012.

During a recent appearance on TBS' Conan, Ke$ha opened up about her highly unusual songwriting process. "I turn off all the lights and I walk over to the piano and I gently lower myself -- my boobs -- onto the keys and I just let 'em tickle the ivories," she said. "They really just go crazy. Then all of a sudden, I have these chord progressions."

The My Crazy Beautiful Life star added, "It started a joke, but it seriously has produced some of my favorite songs on my new record."
