The red carpet wasn't packed with celebrities last night at the MGM Grand in Las Vegas for the 2014 Billboard Music Awards, but we spotted a few stunning looks from some of our favorite stars. Ludacris did his best LL Cool J and hosted for the night and Jennifer Lopez received an Icon Award. She was stunning on the red carpet, opened the show and performed again before accepting her award, pretty flawless, we must say. From Nicki Minaj, to Kelly Rowland, John Legend and Jordin Sparks, there was lots of black and cut-out looks on the red carpet as well as some questionable looks...we'll leave you to be the judge of those. Take a flip through our slideshow!
