Rihanna has teased on how her next album will sound like. When met at the after party of her "Last Girl on Earth" tour in New York City hotspot Greenhouse on Thursday night, August 12, the "Rude Boy" hitmaker shared to Just Jared her excitement over her follow up album to "Rated R" and added it will sound "strong, fun and sassy."

In the meantime, the 22-year-old singer has dazzled the crowd who watched her Madison Square Garden gig. After an opening performance by Ke$ha, she came out to the stage wearing a black gown fit for a funeral, and began singing "Russian Roulette". After a quick change, she continued on with "Hard", during which she very proudly rode her own baby-pink military tank.

Before belting out a medley of "Love the Way You Lie" and "Airplanes", the girlfriend of Los Angeles Dodgers outfielder Matt Kemp shouted, "Is New York City in the house?" Just after singing to "Hate That I Love You", she lounged sexily on a chaise to deliver "Rehab" and then spiced things up with "Te Amo". "Don't Stop the Music", "SOS" and "Take a Bow" came thereafter.
