JoJo Siwa attended the AMAs, donning an elegant dress that is nothing like anything we've seen her wear before.

The dancer and singer took part in the ceremony on November 21, stunning fans and fellow celebrities by rocking a black gown with a ruffled, sheer skirt and an off-the-shoulders bodice. Siwa revealed her mother had picked the dress for her.

JoJo Siwa Sent Her Mom To Get Her A 'Mature Outfit' For The AMAs

In an interview on the red carpet tweeted by Access Hollywood, the 18-year-old 'Dancing With The Stars' contestant said: "I sent my mom to the store. I said 'mom, I need a mature outfit.'"

Siwa then revealed her dance partner on the show, Jenna Johnson, had gifted her the sparkling heeled shoes she was wearing. And not just any heels: Siwa was wearing her first-ever pair of Louboutins.

"Jenna showed up today, she got me heels. She bought me my first-ever pair of Louboutins," Siwa said.

As well as the shoes, Johnson gave Siwa some advice on how to walk in heels.

Siwa said: "We did a rumba on 'Dancing with the Stars' a few weeks ago and Jenna told me 'do rumba walks.'"

"I've been taking rumba walks every step that I take and it helps," she added.

The YouTube personality and Nickelodeon star also traded her signature pony tail with a bow for a chic half-pony with her hair down in curls.
