The image shared on June 2 shows Harper giving her dad a kiss on the lips — a sweet moment which the adoring father wanted to share with his fans.
"Why do this? We don’t need to see it," one person wrote in the comments.
"To be honest kissing your daughter on the lips is a little weird... yes it is," another added.
"I try not to judge but I can’t help but think it’s pretty weird that he kisses her on the lips considering her age," a third commented.
Others were quick to point out that it's totally normal to give your young daughter a kiss on the lips, and that it's nice to see the affection he has for her.
"Lovely photo showing the sweet connection between you and your daughter," a fan wrote.
And now, Beckham has broken his silence about the controversial post, saying it's only natural to show your kids affection.
"I got actually criticised for kissing my daughter on the lips the other day. I kiss all my kids on the lips," he said In a Facebook Live discussion, The Telegraph reports.
"Brooklyn, maybe not. Brooklyn’s 18, he might find that a little bit strange. But I'm very affectionate with the kids. It's how I was brought up and Victoria, and it’s how we are with our children.
"We want to show our kids love and we protect them, look after them, and support them, and we’re very affectionate with them."
