Big Time Rush is an American television series that originally aired on Nickelodeon from November 28, 2009 until July 25, 2013.
It was created by Scott Fellows (also the creator of Ned's Declassified School Survival Guide and Johnny Test and the head writer of The Fairly Odd Parents).
Regarding her Victorious character, Gillies said "It’s wonderful. I always say she’s not so much the “mean” girl, but the “bad” girl in so many ways.
This marked her second time working alongside 13 co-star Ariana Grande.
In the summer of 2008, Gillies was cast as Lucy in a Goodspeed production of Jason Robert Brown's new musical 13, alongside her future Victorious co-star, Ariana Grande.
Later that year, 13 moved to Broadway, which made it the first Broadway production to have a cast and band entirely made up of teenagers.
Desperate to get James to the tryouts, they make a phone call to their respective mothers, looking for a ride. They finally strike a deal with their lady neighbor for a ride to the tryouts with a trade for shoveling snow for her for the rest of the winter.
When they arrive, the boys soon discover that the producer Gustavo who is judging for the talent search is cliche, mean, and sends out hopeful after hopeful, often in tears.
