Pop music sex symbols Rihanna and Miley Cyrus let it all hang out last night while attending the 2014 amfAR Inspiration Gala, a charity benefit for AIDS research. TMZ published some snap shots from the event. As you can see, they turned a lot of heads and stimulated a lot of attention for the evening. Hopefully they translated that titillation into donation.
