Tonight at the 2012 Grammy Awards, pop stars hit the red carpet for pictures prior to the big event. Like any other A-list award show, stars like Adele, Bruno Mars, David Guetta, Kelly Rowland, Wiz Khalifa plus many more hit the red carpet at the 2012 Grammy Awards dressed to the nines.

Bruno Mars looked adorable and dapper from the waist up, but the pants of his grey suit just seemed a tad too short, making the crooner's legs look a bit short. We love the little peep of color from his orange socks, though! Adele looked absolutely stunning on the 2012 Grammy red carpet in a sparkly black, floor-length gown with sleeves. Her red locks have a strawberry blond hue now, and her rep lipstick really tops off the look. Kelly Rowland also looked beautiful on the red carpet at the 2012 Grammy Awards, wearing a form-fitting peachy-colored gown with jeweled embellishments.
