Wayne and the pop songstress recently collaborated on a few songs for his band's upcoming EP The Flaming Lips and Heady Fwends.

The musician and his group met up with Ke$ha at her home in Nashville, Tennessee.

Ke$ha greeted Wayne and friends with a tattoo gun.

"Most of the time, if someone's willing to work with me, they're going to be a freak," Wayne told MTV News. "And Ke$ha ... I sort of thought that she would be a freak, I'd heard about her and we'd tried to get a hold of her earlier. We showed up at her house, and she has a tattoo gun that she gives everyone a tattoo with, so within 20 minutes of being at her house, I had a tattoo on my toe; it's the only tattoo I've ever had."

"We were set to do this one song that I had prepared, and we went into the studio that night, and stayed there until about two in the morning, and did four songs, just making stuff up. And the next day [we] worked for another couple hours. She's funny, she's gracious, she's imaginative, she's creative and she's a lot of fun to be around." (C) Cover Media
