Unclear who will be in the rest of the field dancing against the Olympian -- the full lineup is expected to be announced next month -- but ya gotta figure the gymnast will be a big favorite to win The Mirrorball Trophy.
After all, she KILLED IT in Tokyo ... winning the gold medal in the all-around competition, silver in the women’s team competition and bronze in the uneven bars.
Not sure how well that all translates to the salsa or the waltz -- but, hey, it can't hurt!!
FYI, this won't be the first time a gymnast competes on "DWTS" --- in 2016, Laurie Hernandez won the competition ... and, in 2017, Simone Biles finished fourth.
