OK, so, nothing is official yet, but Miley fans are abuzz with the possibility that the actor-singer could have gotten engaged to boyfriend Liam Hemsworth. On Thursday, she posted a picture of her new nails on Twitter, and her followers couldn't help but notice the giant diamond ring on her finger.

Last night, Cyrus made another public appearance alongside Hemsworth, who is currently starring in The Hunger Games. The couple were as couple-y as usual, and Miley was still sporting that diamond. Although she's only 19, Cyrus has been dating Hemsworth for some time — they met on the set of the dreadful Nicholas Sparks adaptation The Last Song.

The couple already co-parent one "child," a puppy named Ziggy.
