(CNN) Male dancers protested outside the studio while Lara Spencer formally apologized Monday on "Good Morning America" for her recent comment mocking Prince George's interest in ballet.

"I screwed up," Spencer said on air. "The comment I made about dance was stupid and insensitive and I am deeply sorry."

Controversy arose last week after "GMA" aired a segment that mentioned that the future king of England's favorite activities include ballet lessons.

"We'll see how long that lasts," the GMA co-anchor deadpanned about the 6-year-old's interest before chuckling.

Viewer response was swift, with even dance legend Debbie Allen offering a video rebuttal on social media that was posted with the hashtag #boysdancetoo.
