JoJo Siwa Cuts Off Her Ponytail in Surprise Hair Transformation

JoJo Siwa is changing things up and going with a new hairstyle. As she wrote on Instagram, “Mayyyyy have done something todayyyy.”

Attention, Siwanatorz! This is not a drill: JoJo Siwa has cut her signature ponytail. 

The 18-year-old Nickelodeon star revealed she went for the chop in a video posted to Instagram on Wednesday, April 6. "Mayyyyy have done something todayyyy," JoJo captioned footage of her strands getting snipped away as Demi Lovato's "Cool for the Summer" played in the background.

Before the YouTuber debuted her final look, her friends and fans couldn't wait to see the results. "Ahhhhh!!!!!" Dancing With the Stars pro Sharna Burgess wrote in the comments section. Added TikToker Avery Cyrus, "YESSSSSS!" And on April 7, JoJo posted a picture of her new shorter style to Instagram along with the word "HAPPPPPY."

Perhaps the change shouldn't come as a huge surprise. After years of sticking with the tried and true high pony, JoJo has tried out several different hairstyles. From taking out her bow and wearing her hair down to dyeing her blonde hair brunette, the "D.R.E.A.M." singer has donned a number of 'dos in recent years.

"It's hilarious," JoJo told Entertainment Tonight in June 2020 after a video she'd posted with her hair down went viral. "I knew it would be a shock to people...I knew it was going to be like, 'Oh my gosh, JoJo put her hair down,' because people just don't see that. But I also did not expect it to go as crazy as it did."

The new tresses aren't the only update in JoJo's life. Just last week, she shared that she's dating someone. "I am not single and I don't want to mingle," JoJo, who was previously in a relationship with Kylie Prew, said on the March 30 episode of the Rachel Uncensored Podcast. "No, I'm a loyal lady."
