Lara Spencer's comment on Prince George taking a ballet class ignited a movement on social media among boys who dance – and the parents who support them.

Following the "Good Morning America" host's reaction to the 6-year-old for loving ballet, which she has since apologized, social media has flooded with photos and videos of boys dancing along with messages firing back at Spencer. They are using the hashtag #boysdancetoo.

Most of the tweets said the journalist's response could not only hurt Prince George, but their sons and the dance community as well.

"On behalf of my amazing ballet-trained son, more fit and athletic than you’ll EVER be, please STOP ridiculing things you have no knowledge about," wrote Kristina Witzling to Twitter. "Thank goodness he hasn’t had useless people like you in his life!"

A mom, who goes by the name Mariana on Twitter, said her son is a ballet dancer and one of the "most hard working and dedicated, kind young men" she's known and that dance brings him joy.

Another mom added that comments like Spencer's are the reason that her kid is scared his friends will find out about him dancing.

In a clip published Thursday, Spencer, 50, brought up the young royal's back-to-school plans on the morning talk show.

"Details of George's curriculum have been released, making us all really happy we don't have to do homework anymore," she said. "In addition to the usual first or second-grade things like math, science and history, the future king of England will be putting down the Play-Doh to take on religious studies, computer programming, poetry and ballet, among other things."

The clip then cuts to images of the 6-year-old, but laughter can be heard from the "GMA" set.

"Prince William says George absolutely loves ballet. I have news for you Prince William, we'll see how long that lasts," Spencer added, before letting out a chuckle.

Spencer has since issued an apology and sat down with three prominent ballet dancers on "Good Morning America."
