Long before she collaborated with Diddy on her hit debut single, "Tik Tok,"
Ke$ha wrote the title track from Miley's hit EP The Time of Our Lives and said that the singer, who was recently praised by Timbaland, was a lot of fun to work with. She added that when she was writing for the "Hannah Montana" star, she took her formula for writing party songs and applied it to Miley's tween audience. The result? A bouncy, Auto-Tune-filled pop ode to — what else? — having a good time.
"Well, like I said, I just write all the time 'cause it's all I can do," Ke$ha told to MTV News. "Writing for Miley was fun 'cause I think she's funny. I met her and I liked her vibe, so I was like, 'OK, I'll write, like, a party song for a younger crowd.' ... And that was fun just because I like her."
Ke$ha also had the distinct pleasure of appearing on Britney's Circus song "Lace and Leather." And while she never got the chance to meet the pop star, she said the project came at just the right time.
"And for Britney Spears, I just did backgrounds for her 'cause I was so broke. I needed to pay my rent," she said. "I got a few bucks. No, [I didn't meet her]. I just did backups for her."
