Ariana Grande was the second performer tonight at the 57th Annual Grammy Awards. Taking on her Harry Styles-penned ballad "Just A Little Bit Of Your Heart" off her latest album My Everything, Grande performed inside a circle of neon ice cycles, alongside a white grand piano and string section. Dressed in a long black dress and her signature ponytail, she delivered the song without too many vocal hiccups and seemed genuinely excited to be there.

Among Grande's nominations at the 2015 Grammy Awards are Best Pop Vocal Album for My Everything, competing against Miley Cyrus, Katy Perry, Coldplay, Ed Sheeran and Sam Smith, and also Best Pop Duo/Group Performance for "Bang Bang!"

Grande is just one of many artists to perform at the ceremony tonight. Madonna, Gwen Stefani, Adam Levine, Katy Perry, Sia, Lady Gaga & Tony Bennett, Rihanna, Paul McCartney, Kanye West, AC/DC, Eric Church, Beck, Chris Martin, Sam Smith, Mary J. Blige, Beyoncé, Common, John Legend, Ed Sheeran, Herbie Hancock, John Mayer, Questlove, Juanes, Pharrell Williams, Usher, Miranda Lambert, Tom Jones & Jessi J, Hozier, Annie Lennox, and more either have or will grace the stage over the course of the evening.
