• James Charles gave JoJo Siwa a dramatic makeover on his YouTube channel.
• The beauty influencer traded Siwa's signature glittery makeup and ponytail for a more understated look.

• In the video, Charles shared that he'd been trying to feature the former "Dance Moms" star for almost two years before she appeared on his channel. Siwa shared that she typically doesn't let others do her makeup.

YouTube creator James Charles completely transformed former "Dance Moms" star-turned-influencer JoJo Siwa with a dramatic makeover.

Charles shared his video, "Giving JoJo Siwa a full makeover," on Friday. He said that the collaboration between the two stars has been nearly two years in the making.

Siwa shared that she typically doesn't let others do her makeup

"Getting my makeup done number one is just like a 'no.' I like to do it. I don't let anybody else do it. My hair, even more so," she said at the start of the video.

Charles began the makeover by removing Siwa's signature colorful, glittery makeup so he had a blank canvas to work with.

While he applies foundation and concealer, the pair spoke about Siwa's rise to fame after she first appeared on the reality TV series "Dance Moms" in 2013.

"I know that I would be nothing without 'Dance Moms' — it's where I started, it's what got me my platform," she said.

Since her appearance on "Dance Moms," Siwa has become a Nickelodeon star and created her own fashion line, JoJo's Bows, which has sold millions of sequined accessories.

Charles applied winged eyeliner and deep brown eyeshadow on Siwa, then added a mauve lip color. Then, he took her off-screen to add finishing touches.

Charles traded her signature high ponytail for a sleek wave.

Siwa commented that she thought Charles did "a wonderful job" on her hair and makeup, but added that it's not her style.

"Obviously it's not me, I mean, you know how I showed up here in sparkles and bright pink and neon and rainbow, but it is really pretty," she said.

Many fans also commented that the look was a big departure from her typical style.

"I didn't recognize her at first," a fan wrote on Charles' Instagram post.

Some fans compared Siwa's new look to a "younger version of NikkieTutorials," or Nikkie de Jager, another YouTube beauty influencer.

In exchange for her makeover, Siwa gave James Charles a "JoJo Siwa Makeover" on her YouTube channel.

Representatives for James Charles and JoJo Siwa did not immediately respond to Insider's request for comment.
