Slater and Sosa are going to be hosting a TikTok Live during the Instant Dance Challenge, which will take place in the show's second hour. This is the first time that DWTS pros will be going live on social media during the live show.

In order to watch Slater and Sosa, fans will want to follow the "@officialDWTS" TikTok account.

"BIG ANNOUNCEMENT!!!! Happening today!! Stay calm everyone, STAY CALM," Slater captioned a video shared on Instagram earlier in the day. She and Sosa teased the news and confirmed it was about the 500th episode, which is set to air on ABC on November 12.

Just after Sosa and Slater made their big announcement, fans took to the comments section to react. Most fans really love the idea and are excited.

"OMGG THIS REALLY IS A MAJOR ANNOUNCEMENT!!!" a third comment read.

Shortly after the announcement tease, dozens of fans commented on the social media posts. Many fans took some guesses about what the announcement would be while others let Sosa and Slater know they were worried about "disappointing" news.

"YA'LL ARE GONNA LOVE IT SO EXCITED TO TELL YOU GUYS!!!" Sosa commented on the same video shared on Slater's TikTok.

"I love you Ezra but if this is a disappointing announcement I will cry. Plz don't disappoint me," one fan responded.

"It's not," Slater said, reassuringly.

"Y'all better not be playin w me rn," another comment read.

All kinds of guesses from Sosa co-hosting the "Dancing With the Stars" tour, to no elimination on Tuesday night flooded the comments section.
