Rumer Willis has to sit out of the "Dancing with the Stars: Live! Perfect Ten Tour."

The 26-year-old actress and singer revealed she has injured her foot and therefore cannot dance for a while on the tour. She did not disclose the length of recovery time she's looking at.

"I have to hang up my dancing shoes for a little bit because of a few stress fractures in my foot but it's not gonna stop me from singing for you guys on the #DWTSlivetour," Willis captioned a black-and-white photo of her foot in a brace on Instagram Thursday morning.

The twentieth-season winner of Dancing with the Stars joined many show pros for the 25-date tour this summer, which kicked off June 13.

Just three days ago, Willis took to Instagram to gush about how much fun she had been having on the tour.

"I have had such an amazing time on the #DWTSlivetour so far...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," Willis wrote alongside a photo of herself and Val Chmerkovskiy onstage.

Willis had won the special golden mirrorball trophy with Chmerkovskiy, her professional partner, back in late May. Their victory was special because it had fallen on the ABC reality dancing competition's tenth anniversary.
