Rihanna has insisted on having a party at M2 tonight to celebrate the release of her new album, “Rated R,” with her fans who were locked out of her official industry party that attracted the likes of Jay-Z and Tyson Beckford last week. The pop star has flown in her favorite deejay, Khaled, from Miami, to spin at the West 28th Street hotspot. The diva will take to the stage to greet fans, and M2 mixologist Jim Sanders has created three fierce drinks named after her chart-busting singles, “Hard” and “Fire Bomb.”
