We spotted Usher (along with producer Rico Love) arriving at the Mirage Hotel and Casino for the iHeartRadio Music Festival in Las Vegas over the weekend. The singer was one of the performers in the major lineup for the festival, which also included Rihanna, Mary J. Blige (who brought out Prince!), and Pitbull. Usher was arriving with singer and songwriter, Rico Love, dressed in all black with a green leather jacket. Peep the photos.
