"I have to hang up my dancing shoes for a little bit because of a few stress fractures in my foot," Willis, 26, shared with a pic of her foot in a boot. "But it's not gonna stop me from singing for you guys on the #DWTSlivetour."
"I have had such an amazing time on the #DWTSlivetour so far," she wrote on Monday. "I am so grateful to be able to keep dancing not only for myself but for all of you guys. Feel so lucky to be sharing the stage with such incredible people and a huge thank you to @iamvalc for continuing to help me grow as a dancer everyday."
