What's going on here then? Mel C has denied rumours of a romance with Matt Cardle, but a steamy kiss on-stage at G.A.Y could fan the gossip flames again.
The pair have teamed up for a duet together called 'Loving You', which was officially released on 18 August. They performed the song together at G.A.Y on Saturday night, and re-enacted the steamy snog they share on the single's video.
Matt recently told the South Wales Argus
about how the song came about, saying: "We basically met at the Isle of Wight Festival last year. Mel was playing on the same stage as me so we had a quick chat then.
"I then met her this year at a Cancer Research fundraiser. We swapped numbers and I invited her to my concert in London in May. We spoke after the show about writing together."
But after the smoochy video was released, of course, romance rumours circulated
. But Mel recently told Digital Spy
: "Matt is gorgeous and he's not a bad on-screen boyfriend to have, but we're just mates. We were both so nervous about getting steamy together.
"I've never had to be passionate with anyone in a music video before, so it definitely took some courage."
And, apparently, they had a little practice run in the dressing room before shooting started on the vid
But, it seems, for now the relationship is strictly professional - but they put on a good show, don't they?
