If you needed any more proof that Miley Cyrus and Liam Hemsworth are back together, you don't need to look any further than the singer's Instagram. Her latest selfie features some very serious bling on her left ring finger - and it probably looks familiar to superfans.

People reports that the diamond is a dead ringer (no pun intended) for the Neil Lane engagement ring Hemsworth gave to Cyrus in 2012. Cyrus doesn't mention the ring in the caption, focusing on her green polka dot outfit instead. ""#looklikemyf---ingmomdressedmethisam #prettysureihadthissamelookat6," she wrote.

Rumors that Cyrus and her ex-fiance were reigniting the flame began earlier this month when they were spotted canoodling at an Australian music festival. The couple split in 2013, but TMZ reports the "Wrecking Ball" singer is moving back in with The Hunger Games actor.

Do you think that's the old ring?
