Titled "Will You?", the photo collection captures several couples at different stages of their relationships including two men ready to propose to each other.

The advertisement reads: "Will you promise to never stop completing my sentences or singing off-key, which I'm afraid you do often? And will you let today be the first sentence of one long story that never ends?"

The 22-year-old singer took to social media to share her thoughts on it, reports eonline.com.

"Thank you Tiffany & Co for being so bad a**!!! F--kkkkk yasssss," Cyrus captioned the picture on Instagram.
