Two days after the news of Miley and Hemsworth’s break up, while still enjoying her time in Italy, Brandi posted a vacation photo on social media with a cryptic caption — a possible hint to her younger sister’s split.

“I’ve learned that life sometimes takes us through seasons when we cannot understand why things have to hurt so much or be so hard, but all we can do is trust that there is a purpose in everything, even the darkness,” she wrote underneath a photo of herself in a neon orange bikini with the breathtaking views of Lake Como behind her.

“In time everything will make sense, and all of that purpose will be revealed when the time is right, and we will be stronger and better for it,” she continued.

Rumors of a split between Miley and Hemsworth, 29, began after the “Mother’s Daughter” singer posted a photo of herself on Instagram in which she wasnot wearing her wedding ring. A source told PEOPLE the two actually split months prior.
