To kick off the official debut of her new album, Animal, singer Ke$ha performed her hit song “TiK ToK” on The Ellen DeGeneres Show today.

Never heard of Ke$ha? Well, the 22-year-old is now linked to two of the hottest tracks…ever. Just last week, the singer sold 610,000 downloads of her current single—that’s the best number for any female artist in recorded history. The overall title still belongs to Flo Rida’s “Right Round” (636,000)—another song Ke$ha can be heard on.

Oh - and in case you wondering about the spelling of her name, Ke$ha - born Kesha - recently explained that dollar sign to Entertainment Weekly:

“I was on the Flo Rida song ‘Right Round,’ and I was hearing it everywhere, just all over the place. It was number one in a bajillion countries and I didn’t have enough money to buy myself a taco. So I was talking to one of my friends about it and I was like, ‘What the hell!’ I literally had two dollars to my name, and she was like, ‘Whatever, you don’t need money: You’re money.’ And I was like, ‘Yeah! I’m money!’ So it’s really just me taking the piss out of the fact that I was broke while being on a number-one record. It’s actually just being ironic about the whole money thing, because I actually stand for the opposite of putting a lot of emphasis on money.”
