Ke$Ha and rapper will.i.am decided to work together on new track Crazy Kids after bonding in the studio over shots of tequila.
The stars were in the sound booth working on separate projects when they realised they shared a common interest, a love of drinking, prompting the two to hit it off and plan a songwriting collaboration.
Ke$ha recalls to MTV.com, "We were recording next door to each other, and we played this fun game that was, 'We're gonna play our music louder than the other one.' So by the end of the week, we both had just taken over the studio and we would go back and forth and take shots with each other and run around. He's like totally crazy also. And, you know, I feel like we just really vibed with each other.
"He's really positive energy and he's really fun. He's very childlike, which I feel like I'm kind of that way also. We just wrote this (song) quickly... Tequila's a very unifying thing."
The Tik Tok hitmaker insists she is proud of the new track: "He and I wrote the song together, so it seemed like a natural thing for him to be on it, and his verse is really funny; he talks about boobies. Anytime somebody says anything about boobies, it's great - love it."
