Stay (2013)

If Rihanna asked you to take a bath with her, you'd be crazy not to Stay (2013). The video for this slow, piano-driven track gives us an unusually SKINtimate look at the pop princess as she soaks in a tub full of murky water; this being a music video and all, we don't get to see any of her good parts, but the Barbadian diva is so red hot, it's still worth pulling up a chair and Staying a spell.
