Ke$haKe$ha brought her party-ready pop anthems to the 'Today' show on Aug.13. The singer performed live in Rockefeller Plaza, opening her set with her debut hit 'Tik Tok.'

"I'm so excited," Ke$ha told host Matt Lauer, who then asked her about the origin of her stage name.

"It was just me being ironic," Ke$ha explained. "I was really broke when I wrote this record. Instead of having a pity party, I thought I'd turn it into an ironic statement."

Ke$ha, now on tour with Rihanna, then performed her latest single, 'Take It Off.' Watch the videos. >>
