JoJo Siwa is ready to cast her vote!

While attending the Christian Cowan SS25 show as part of New York Fashion Week on Sept. 8, the actress and singer, 21, opened up about how she plans to support Anna Delvey when she competes on season 33 of Dancing with the Stars.

"My best friend in the whole entire world, Ezra [Sosa], it's his first season as a pro, and he's partnered with Anna Delvey, so I've got to vote for them," Siwa tells PEOPLE exclusively.
