Embarrassed Lars Lerin sings on his husband's new single

"With every take, Junior got excited and wanted more energy, more energy. So I sound completely fired up on the recording," Lerin tells the magazine.

It's so embarrassing that I don't know what to do with myself.

Junior Lerin is all the more pleased.

Lars, he's a favorite with old ladies, but the kids like me. So we complement each other very well. Together we capture Sweden, he says.

The song "Skaka bunda" will be released on May 8. It, like Junior Lerin's hit "Copacabana Boy", was written by Fredrik Andersson.
