The Strictly Come Dancing professional dancer, who was partnered up with Ranvir Singh on last year’s competition, posted a picture of himself standing behind the singer as he planted a kiss on her cheek.
Giovanni, 30, posted the picture on his Instagram story as he wrote: “Miss you !!! @alexandraburke,” with a red love heart emoji.

Alexandra was then seen flirting back with the BBC star by re-sharing the picture onto her own story, adding: “I miss you you more baby!! pernicegiovann1.”
The X Factor winner, 32, partnered up with Gorka Marquez while she competed on the dancing competition back in 2017, while Giovanni paired up with Debbie McGee.
OK! online have approached Giovanni and Alexandra’s representatives for comment.
It comes after Italian professional dancer Giovanni was linked to his recent celebrity dance partner Ranvir, 43, while they were competing on the show last year.
The stars danced away on Strictly in 2020 and even exchanged late night texts with one another.
It came after Giovanni shared a screenshot of their messages on Twitter where the GMB host said: “I’ve woken up and I’m doing the jive in bed,” alongside a hand over face emoji and a crying with laughter emoji.
He tweeted: “And the semi final weekend has officially started, while also adding: “That’s what I call commitment .. 3.19 am @bbcstrictly @ranvir01.”
While many were speculating over their messages, fans also spotted that Ranvir had set her WhatsApp profile picture to a snap of herself and Giovanni.
The picture saw them rehearsing on the dance floor, with Ranvir arching her back to practice one of their many routines.
Jamie Laing, who reached the final with Karen Hauer last year, spoke out on the speculation last year, as he said: “I think Giovanni fancies Ranvir, that’s what I think. I am in love with Giovanni and I’m in love with Ranvir, so I’d be jealous of either one of them if they started hooking up with each other.
“I just think they’re incredible friends, they’re amazing partners. You have to remember that they’re putting on a performance. When you’re putting on a performance, it’s about making people believe it.
“If people at home are believing they’re in a relationship, then they’re doing their amazing job together, that’s incredible. They’re such a beautiful partnership, it’s amazing.”
