The 24-year-old singer took a moment to pay tribute to those affected by the Manchester concert tragedy during her appearance on Tuesday's finale of The Voice.
"I'd like to dedicate this song to my good friend, Ariana Grande, and everyone who experienced that horrific attack yesterday [Monday]," Cyrus said before performing her new single, "Malibu." "Our hearts are with you."
Wearing minimal makeup and choosing to leave her blonde locks down, Cyrus looked serene in a white bohemian top and matching shorts as she stood among a sea of flowers and greenery and crooned the song's romantic lyrics.
Cyrus posted a black-and-white photo of her and Grande on Monday, writing a touching note to her pal.
"Wishing I could give my friend @arianagrande a great big hug right now... love love love you .... so sorry you had to be apart [sic] of such a tragic event!" she wrote. "My most sincere condolences to anyone and everyone affected by this horrific attack! all I can do is send as much HOPE & PEACE your way! This MUST end! No more war .... no more innocent lives taken .... L-O-V-E."
