The "Rated R" songstress will appear as guest performer on Saturday Night Live featuring Blake Lively (December 5).
The episode will air a day after Rihanna is guest on The Ellen DeGeneres Show (December 4).
Rihanna is photog'd (above) leaving her album release party at Juliet's Supper Club in New York (November 24). She promoted her rockstar persona with a silk, red mini-dress; complimented with long sleeves; a gathering, deep cleavage line; and silver spikes and chains adorned from her shoulders to neckline.
Her black heels reached above the ankle, on top of sheer leggings with a black and white trim.
