In a video shared on the show's Twitter account, Siwa expressed her eagerness to get started on the show. "I am so excited to be a part of this year's Dancing With the Stars season 30, and to be dancing with a girl," she said in the video. "I think it's so cool ... I can't wait to dance every week, I can't wait to meet my partner, oh my gosh, there's so many things I'm so excited for!"
Dancing With the Stars also announced that 18-year-old Team USA gymnast Suni Yee will also be joining the show's 30th season, hot off of her gold medal win in women's gymnastics individual all-around at the Tokyo Summer Olympics. Both Siwa and Lee are set to appear on Friday's episode of Good Morning America for a sit-down interview about their casting, before the full cast of season 30 is revealed Sept. 8.
