Hilary Duff tells Twitter fans to kiss off if they don't like this picture

Hilary Duff had a great day at Disneyland with her 4-year-old son, Luca Comrie. To commemorate the moment at the "happiest place on Earth," she posted a picture of her with Luca in front of It's a Small World, mouse ears and all. The picture had one apparently noteworthy detail: mother and son were kissing on the lips.

We apologize, this video has expired.

Most of the comments under the picture were supportive. "So sweet!" said one fan. "You two are adorable!" said another. But a few comments were not. "Oh my!... get a room!" tweeted someone with the Twitter handle @cliffordblack5. "You're sick.

Quickly, Duff clapped back at any real or potential haters. "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 judgment," she tweeted. The tweet has been liked over 3,800 times so far.

This summer, Victoria Beckham (aka Posh Spice) also found out that the denizens of the Internet sometimes have opinions on parenting styles. In particular, some took issue with this picture of Beckham kissing her youngest child, Harper, on the lips in this post wishing her a happy fifth birthday in July:

After her photo garnered over half a million likes on Instagram and 4,000 comments, most of which were positive and supportive, the BBC consulted a "social etiquette expert," Liz Brewer, on the controversy.

"Normally with a member of your family you don't kiss on the lips unless it's your husband," Brewer told the BBC. "I would be uncomfortable doing that and I think most people would be. If she feels it's appropriate, so be it. I wouldn't say it sets a particularly good example."

Duff's tweet implies she agrees with Brewer on one thing: it is her decision whether or not it is appropriate for her to kiss her son on the lips. And in a poll by TODAY Parents, 72 percent of respondents agreed that kissing your own child on the lips is fine, and only seven percent said it was never okay.

So Duff can feel good about the sweet moment she captured with her son...and justified in her assertion that haters can just kiss off.
