It's cool. Laughter is usually a good thing.

Jessica Simpson isn't my usual cuppa tea but occasionally I enjoy a bit of pop, you know. I do think she has a good voice, but most of her songs suck. Don't get me started on her remake of Berlin's "Take My Breath Away"!
As for Willy, I think he sings harmonies for her. Though she has lowered her voice to a Britney Spears-esque purr for the song, she and the throbbing hiphop/pop country beats completely overwhelm his voice. If I hadn't seen the video, I wouldn't have known he sang on the track at all.
