It was only a few weeks ago that Jessie confirmed she was dating musician Luke and now their romance seems to be hotting up.
Cuddling up to each other on arrival to the event, the 'Do It Like A Dude' singer and her other half looked like the perfect pair.
While Luke looked effortlessly cool in his leather jacket and studded ankle boots, Jessie oozed sophisticated glamour in a tailored white suit.
Keeping her raven locks sleek and straight, Jessie opted for a monochrome themed ensemble, teaming her two piece with a black box clutch and matching sandal heels.
They certainly make one fierce couple, don't cha think?!
Both Jessie and Luke had big smiles on their faces as they posed together and in one cute snap, Jessie can be seen looking lovingly at her man.
The pair's red carpet debut at the AMAs comes after Jessie recently gushed she was "really happy" with Luke while appearing on Loose Women.
Opening up about her relationship, the former Voice coach admitted it was still "early days", but she said she thought her boyfriend - originally from New Orleans - was "incredible".
In the past Jessie has kept her love life private, but speaking to the panel, the 26-year-old said getting older has made her realise she wants to share her happiness with others.
"I've realised I can't experience like everyone else if I hide it," Jessie explained. "I'm famous, it's never going to stop...
"As you get older you experience different kind of love through your life and I've got to the point where I want to celebrate someone that I've found."
