Sweetin will be partnered with professional dancer Keo Motsepe, who joined the series in Season 19.
"I would have loved to do it in the past, but it was a huge scheduling conflict with Fuller House at the time, so I wasn't able to do it," Sweetin explained.
"I'm a huge fan of the show ... I've always loved to dance ... [but] I definitely don't call myself a professional."
"I'm dancing with Keo," she announced.
"We have just had the first couple days. It's so fun. We got through some basic moves of several different styles of dance. We had a lot of fun with it and he and I get along really well ... He's a phenomenal dancer and such a doll."
