Photo Flash: Ariana Grande Celebrates New Single, 'Put Your Hearts Up,' in Times Square!

Ariana Grande, currently starring in Nickelodeon's 'Victorious', recently released her new single  ('Put Your Hearts Up') on December 20. The teen star - who was seen on Broadway in Jason Robert Brown's 13 - appeared in Times Square's Planet Hollywood in support of the single. Check out photos below!

Victorious follows Tori Vega (Victoria Justice) a teen who unexpectedly finds herself navigating life at an elite performing arts high school. After her sister Trina (Daniella Monet, Nancy Drew) has a medical mishap on the night of the school's annual talent showcase, Tori steps in to perform Trina's song. Accompanied on the piano by her musically-gifted friend André (Leon Thomas, August Rush, The Lion King, iCarly), Tori's singing and dancing impress the school's principal so much that she offers her the opportunity of a lifetime - an invitation to become a student at Hollywood Arts High School.

From her first day at the school, Tori feels out of place among the students, especially mean diva Jade (Elizabeth Gillies, who also appeared on Broadway in 13). With the help of Trina, André and her new friends - brooding bad boy Beck (Avan Jogia, Spectacular!), eccentric Cat (Grande) and lovable but psychologically scrambled ventriloquist Robbie (Matthew Bennett) - Tori realizes that she was born to perform and that entertaining people not only makes her happy but may change her life. The series will feature original music performed by Victoria Justice and the ensemble cast.
