There is no doubt in my mind that Victoria Justice is a Jori shipper. She liked and reblogged that post from JATMAB, which obviously says Jade Vega and was posted 3 weeks ago. And she’s liked a couple of Jori pics on instagram including the one above.
I don’t know if anyone remembers the time that one of our fellow Jori shippers got Vic to write “Jori is on” during a signing like a year ago, but that happened. So Vic has been aware of Jori and has shown her interest in Jori on several occasions. I think Vic is a definite Jori shipper.
P.S. She broke up Bade in her blog post about the future of the Victorious characters. Obviously she knew that Jade belonged with someone else.
