Beverly Hills, 90210 actor Brian Austin Green has come to the defence of his young son after critics attacked the family for letting him wear a Frozen dress.

The popular Disney film burst onto our screens in 2013 and quickly became a favourite of children across the globe.

With it came plenty of merchandise, including dresses suitable for all children.

Megan Fox, who is married to and has children with Green, shared some Polaroid snaps on Instagram – one of which showed their four-year-old son, Noah, wearing a dress from the franchise.

The picture drew unwarranted criticism from followers.

One wrote: “Probably a million other pictures of her son but she chose to post one of him in a dress! Lol It’s Hollywood! Makes sense! It’s all about the attention and reactions!”

“You should not dress your son in a dress,” another said.

A third added: “A man can’t be a woman and a woman can’t be a man Poor kid is gonna think he can be a girl.”

Speaking in an interview with Hollywood Pipeline, Green came to the defence of his family and insisted that their child would always be able to wear what he felt like.

He said: “He’s 4 and if he wants to wear it, then he wears it.

“It’s his life. They’re not my clothes.

“Obviously I don’t wear the nice stuff. I’m wearing shorts and a T-shirt.”

The star added that both he and Fox felt it was crucial to let their children express themselves.

‘I feel like at 4 or 5 that’s a time when he should be having fun.

“He’s not harming anyone wearing a dress. So, if he wants to wear a dress?

“Awesome. Good on him.” Green added.
