33 year old Jess is a teacher from North London by day and but for the past decade, she's been a singing impressionist in her spare time.
Hoping to ditch the classroom for good and become a full time performer, Jess went before the BGT judges in the first audition show of the series.
In her audition, Jess kicked off her performance with her takes on classics by Shirley Bassey and Julie Andrews.
She then finished with performances of Britney Spears, Sharon Osbourne and Cheryl Cole before getting a standing ovation from the audience.
With such a reaction it was no surprise to see Jess get four yeses from the judges - Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams - securing her spot in the next round.
And if she makes it through to the live shows, Jess has revealed her plans to impersonate the judges next.
“A Judges impression would be great, I would really like to do one and see the reaction," Jess told the official ITV website. "I hope they don’t take offence, I never want to cause offence with my impressions, I think they’re a compliment.
"Yeah just to make people laugh and entertain people. That would be brilliant.”
She added: “I’ve been practising, just in case. Not Simon or David, that’s for sure. I can’t do men. I can’t quite get Amanda right, but I think Alesha is coming on alright.”
As well as a potential Alesha impression, Jess revealed what else we could expect from a potential live show performance: “There are a couple I didn’t do in the Audition which if I get through to the Semi-Finals, I’d love to do, like Shakira and Jessie J… So yeah, that would be fun.”
