Ariana Grande is showing off her sexy side!
While performing at the 2014 American Music Awards Sunday, the 21-year-old singer hit the stage in a sizzling black lace gown that showed off lots of skin. Grande looked elegant yet sexy in the floor-length dress that was see through. Under the hot getup, Grande sported high-waisted black panties and a black bra top. Meanwhile, Grande had her hair pulled back per her signature ponytail style.
Grande began her performance with a soulful, jazz-style rendition of her pop hit "Problem" set only to piano music. No big bass, no flashing lights, just raw, stripped-down vocal talent.
