Even Ariana Grande Couldn't Believe Her Angelic Grammys Performance

Ari sang the heartbreaking song with style.

Everything about Ariana Grande's Grammy performance was sent from above. The pint-sized diva took the smoky stage on Sunday night (Feb. 8), and while she was dressed in an all-white Versace gown on the red carpet, she switched to a long black dress for her performance of "Just A Little Bit Of Your Heart."

Flanked by strings and a gorgeous see-through grand piano, Ari stood alone at the mic, earnestly belting the heartbreaking lyrics, "I know I'm not your only/ But I'll still be a fool/ Cause I'm a fool for you." Ambient blues and purples swelled around her, and after she killed her high notes and ended the song, she clasped her hands of her mouth -- almost in disbelief. Hey, we couldn't believe how heavenly her performance was either.

"Just A Little Bit Of Your Heart" is featured on Grande's My Everything which is nominated for Best Pop Vocal Album. She was also nominated with Jessie J and Nicki Minaj for "Bang Bang."

Ari just finished shooting the video for "One Last Time," also featured on My Everything, and released the lyric video for the song on Friday. She'll be starting her Honeymoon Tour on Feb. 25 in Missouri.
