Are Miley Cyrus and Liam Hemsworth Engaged?! Miley's Flaunting an Awfully Engagement-y Looking Ring!

Is Miley Cyrus ready to say "I do" to Liam Hemsworth? Her ring finger say yes!

19-year-old Miley had been dating Liam, 22, on and off since 2009. Friday night Miley casually posted a photo of left hand on Twitter along with the tweet: "I am soooo obsessed with @jennahipp nail foundations! It looks so chic and classic!"

Of course she made no mention the monster ring on THAT finger (oh Miley, so coy!) but the super-sparkly accessory joined her on the red carpet last night in Phoenix, when she and Liam attended Muhammad Ali's Celebrity Fight Night XVVIII. And she made a big ol' show of posing with her left hand (and that giant ring) on her hip in pretty much every photo from the event.

Reps for Miley and Liam both offered no comment on the couple's relationship status, which doesn't tell us much. (Snooki's rep denied her engagement until the guidette herself announced it on the cover of Us Weekly.)

Of course this could all be a (successful) ploy for publicity on Miley's part. God knows she doesn't shy away from the spotlight. And a little extra publicity over the opening weekend of The Hunger Games—which Liam appears in—certainly could work in her boyfriend's favor.

Do you think Miley Cyrus and Liam Hemsworth are engaged? Do you think that's an engagement ring on her finger? Or do you think she's just messing with us?
