Olivia Wilde is being mommy-shamed over this photo with her son

Olivia Wilde has found herself at the centre of a social media storm after sharing a photo of her and her son.

The actress shared a photo of herself and her three-year-old son Otis this week - and commenters aren't too happy. The snap shows the mum-of-two giving her son a bath, with the photo capturing a kiss on the lips they shared. One person said:

"Kissing your kid like your husband. It's not good for him."

Another said:

"Yeah but it's gross."

https://www.instagram.com/p/BZzSYo2HmHI/ A few others were commenting how the mum is risking making her young son sick. Others were quick to comment on Otis' appearance, with one commenter in particular insulting the toddler. It's not the first time that a celeb mom has been mommy-shammed for kissing her son. Hilary Duff was similarly under fire in December after she shared a photo of herself kissing her then four-year-old son awhile they were at Disneyland. https://www.instagram.com/p/BN8Oa9vBwGS/ She captioned the innocent photo:

"Happiest happiest happiest happiest happiest happiest happiest happiest place on earth! We love you @disneyland."

And while the comments were quick to talk about the photo, the actress was equally fast at addressing the overwhelming response. https://twitter.com/HilaryDuff/status/808720503980621825 She later tweeted:

"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."
