The 2011 amfAR Inspiration Gala for AIDS research went down last night in L.A. -- and while some stars looked flawless on the red carpet, others were a hot mess.
Sandra Bullock, Selma Blair, Rose McGowan and the always sexy Colin Farrell all pulled it together for the event, but there were definitely a couple head scratchers on the arrival line too.
Sinead O'Connor showed up and was once again sporting her infamous bald head while proudly displaying a giant tattoo of Jesus on her chest.
She was seen posing with Debbie Harry, who looked equally bizarre her her black, white and red dress, blond wig and fishnet socks.
Inside, Sinead and Debbie performed for the guests, who sipped Grey Goose cocktails before and dined outside.
