The 20-year-old singer was cheered on by 5 After Midnight's Jordan Lee, Freddy Parker and Brooks Ways' Kyle Brooks as she put on a show at G-A-Y club in London.
Jordan and 5AM are still in the show, while Freddy was the second act eliminated, and Brooks Way withdrew from the competition following allegations about Josh Brooks' personal life.
Gifty posed up a storm with the boys backstage, and admitted on Twitter she had no idea Jordan would be there! After all, he was performing LIVE on X Factor earlier in the evening!
She tweeted: "When @JayLee_Official surprises you and comes to support you at your gig love you."

Gifty and Five After Midnight's Jordan became good friends in the X Factor house; such good friends they have been plagued by rumours of a romance.
Just last week, Gifty told Reveal they have a brother-sister relationship, saying: "There is nothing going on with me and Jordan, everyone keeps saying this!
"We literally fight like cat and dog."
And Jordan told OK magazine: "Apparently, in this industry, boys and girls can't be friends! Me and Gifty share a good friendship and that's all it is. We clash a lot in a good way. Because we're always together, we get photographed together a lot and people perceive it as something that it's not."
Gifty was eliminated from the competition last weekend, in an X Factor moment that shocked many viewers who presumed she was a shoo-in for the final. She lost out when the judges chose to save Four of Diamonds in the sing off, rather than Gifty.
5 After Midnight, meanwhile, are through to next week's Disco Week after impressing with Spice Girls' 'Say You'll Be There' on Saturday's Girlbands vs Boybands show.
Four of Diamonds were the act eliminated on Sunday night after a sing off against Saara Aalto.
X Factor continues Saturday at 8pm on ITV.
