Nia Sioux hosted her blowout Sweet Sixteen party in Los Angeles on Tuesday, June 20th. The Dance Mom star celebrated her birthday with her many A-list friends, including JoJo Siwa, Chloe Lukasiak, and Maddie and Mackenzie Ziegler. (Jojo even told us the cutest things about her bestie, which you can watch in the video below.)

Nia spoke to us about the party’s guests, theme, venue, and perfect dress. The dancer-turned-singer told J-14 that the new music video for her song “You Don’t Really Wanna” would be premiering that very night. She even leaked a major detail of the vid — it’s in black and white.

Lastly, Nia had something she wanted to share with all of her fans: the most important lesson she has learned in the past 16 years.

“The most important thing I’ve learned during the 16 years of my life would probably just to be confident. I feel really confident right now, but I feel like, whenever I was little, I wasn’t as confident as I am. But that would be the one thing that I would say to everyone, that’s just how I feel. I feel really confident,” she dished.

What good advice.
