Big news: Dancing with the Stars just announced the first celebrity joining the cast of Season 30 and...it's JoJo Siwa!

BIGGER NEWS: JoJo confirmed that her dance partner will be a woman, making them the first same-sex partnership EVER on DWTS.
Bring on the sequins and the sparkles. ✨ We’re SIWA excited for this! 🎀 #DWTS @itsjojosiwa
This is a first for Dancing with the Stars in the US, but the British and Australian versions of the show have featured same-sex pairings.
You might know her from her YouTube channel with 12.3 million subscribers, but she's no stranger to dance competitions or reality TV.

JoJo also came out earlier this year, making her the perfect person to mark this moment in DWTS history.
ALSO HUGE NEWS: Olympic gold medalist and international treasure Suni Lee is joining the cast as well!
Suni's got moves, but can she stick the landing on #DWTS? 🏅🌟 @sunisalee_
Suni will follow the long line of US gymnasts who've done Dancing with the Stars, including Simone Biles, Laurie Hernandez, and Aly Raisman.
