London: Melanie Chisholm and Matt Cardle have sparked dating rumors after the pair was caught getting too cozy on the set of their new track, ` Loving You `.
The duo`s passionate kiss in the music video was so steamy that it was briefly trending on Twitter on Tuesday, the Mirror reported.
The former `Spice Girls` star told the publication that she has never had a love interest in a video before, so she was really nervous.
The 39-year-old singer asserted that she has always felt too self-conscious before, and never really had the confidence to do it.
Chisholm insisted that because the song is really sexy, the snog felt relevant and she and Cardle weren`t just doing it for the sake of it.
The mum-of-one jokingly added that it`s not a hardship snogging Cardle.
Chisholm also admitted to the tabloid that both of them practiced kissing each other off-screen, before they filmed the actual video.
