The unsuspecting folks took their spot in that famous red chair. Then, Cyrus and Fallon popped into view with props including umbrellas and a giant hotdog.

On the second day of “Miley Week” the pop star promoted her new album Younger Now by performing the new song “Week Without You” adorned in a long white curve-hugging dress and playing a white acoustic guitar.

“Oh My goodness, you were so good,” Fallon said when she finished. Check out the photobomb gag and performance below:
