Just two years ago she auditioned for The X Factor hoping to make it big in the music biz, and now, Ella is rubbing shoulders with some of the industry's biggest names.
And, making her US red carpet debut on Sunday night, the 18-year-old looked every inch the VIP.
Wearing a floor-length one shoulder dress, Ella looked ultra-glam on arrival to the event.
Keeping things chic and simple in a plain black number, the young singer's dress highlighted her frame perfectly, cinching in at the waist with tie up detailing.
On the beauty front, the 'Glow' singer wore her blonde ombre locks down in loose curls, sporting a bronzed smoky eye and nude gloss on her lips.
Not only did Ella have a seat with her name on at the awards, but the 'Ghost' singer performed her chart topping single at the AMAs pre-show party and she even took to the stage, alongside 'I Need A Dollar' singer Aloe Blacc, to introduce Mary J Blige's performance.
Pretty cool, huh?!
Joining Ella at the awards were the likes of Taylor Swift and her famous girl pals, Jennifer Lopez, the Kardashian sisters and fellow Brits Sam Smith and One Direction.
Taking to Twitter after her star-studded night in LA, Ella tweeted: "Thank you for an incredible evening tonight @TheAMAs x."
Ella's night at the AMAs comes after her recent success since embarking on her solo career earlier this year.
Not only did Ella's first single 'Ghost' debut at number one in the charts here in the UK, but her track also went onto become platinum.
Shortly after, Ella released her first album 'Chapter One' and that too bagged the number one spot.
This weekend, Ella will head back to where it all began as she is due to perform her new single 'Yours' on The X Factor this Sunday (30 November).
And, it seems Ella is pretty excited about heading home.
Tweeting yesterday, she said: "Happy & excited to say that I will be performing my new single #YOURS on @TheXFactor next Sunday! Can't wait to perform back in the UK! E. X"
