1. "I'm baring my soul... and a lot more"
How do you convince your audience that you're shattered over a relationship?
You get naked, literally.
Rihanna did it in her music video for Stay, soaking in a bathtub as we emotional women would like to do. But she's Rihanna, so she doesn't get wrinkly skin when she stays in the water for too long.
Miley Cyrus pulled the same "I'm heartbroken and I refuse to wear clothes" stunt for Wrecking Ball, but the song's more violent edge also had her swinging from an actual wrecking ball, and getting tonguetastically close to other wrecking tools.
2. "I love women and their nudity celebrates that"
Robin Thicke's Blurred Lines music video saw the singer and his collaborators Pharrell Williams and rapper T.I. leer at three barely-clothed models while appreciating their collective hotness in the song's lyrics.
Recently married John Legend loves women, too, notably his model-wife Chrissy Teigen, whose nudity will be on display in the upcoming music video for the single All of Me.
