The Canadian crooner recently appeared alongside Luisana Lopilato on the social media site to chat to fans, with many left concerned when he appeared to interrupt and then grab her at one point – in a clip which has since gone viral.
Luisana took to Twitter to respond to concerned followers, insisting her marriage is in great shape and she remains deeply in love with her husband, and now, a spokesperson for the Feeling Good star has also hit out at the speculation.
“Anyone who watches them on Facebook Live every day can see that this is a beautiful partnership filled with love,” the rep told E! News, adding that the allegations are “a failed effort of cyber bullying” against the couple.
Buble has not yet responded to the controversy himself.
