Hilary Duff can’t believe people are outraged that she kissed her 4-year-old son on the lips.

The actress sparked a heated debate Monday after sharing a snap from a trip to Disneyland where she is seen pecking son Luca on the lips. Though the photo in question received more than 230,000 Instagram likes by the next day, many users spat out their disgust with comments such as, “You should not kiss your son like that. There’s other ways to show love but not that one. It’s confusing for him, it’s not healthy."

Meanwhile, fans of the 29-year-old “Younger” star were quick to jump to her defense.

Duff fired back at her haters Tuesday with a new post that read, “For anyone commenting that a kiss on the lips with my four year old is ‘inappropriate’ go ahead and click a quick unfollow with your warped minds and judgement.”

This isn’t the first time Duff’s photos stirred up controversy. The former child star apologized in October after she and ex-boyfriend Jason Walsh dressed as a pilgrim and a Native American for Halloween.
