Singer Kesha is eager to collaborate with Justin Bieber and Rolling Stones guitarist Keith Richards sometime in the future.
"The range of artists I want to work with is so vast, it's bizarre. I would love to have Keith Richards on the record. I would sure as hell like to do a collaboration with Bieber and at the same time do a song with the Flaming Lips," she told V magazine.
"If someone is a real artist, you can't confine them to a particular genre. It's my mission to make it all make sense somehow," she added.
The 25-year-old singer is very proud of her success so far, but says she still feels like the "dirty little sister" of the biggest pop stars.
"I do feel like there are the pop stars of the world and then I'm like their dirty little sister, running around with s**t on my face in combat boots because I can't walk in heels," she said.
